“I Don’t Want to be Part of Any Jesus Revolution Without a Perichoretic Dance” – Why We Need Both Jesus Manifestoes

Frank Viola and Len Sweet’s book  Jesus Manifesto remains in the Amazon Top Ten today, and my interview with them yesterday has stirred a lot of interesting conversation. Among conversation partners is my friend Jeff Straka, who airs some honest thoughts and frustrations that inspire me to say something I’ve been wanting to say for a long time. Jeff wonders:

While Brian McLaren has endorsed both these authors’ books in the past, his name is glaringly (to me, anyway) missing from the list on this new book. Nor did I find any endorsements from other names considered more solidly in the emergent movement (and not just in “conversation” with). Am I reading too much into this or is this shaping into a “spy vs. spy” manifesto?

Also, are the subtitle words “the supremacy and sovereignty of Jesus” a helpful choice of words as they seem to imply then that other religions are flat-out wrong or false (ala Franklin Graham)?

Well Jeff, we know that Brian rarely eats or sleeps, but even he cannot endorse everything. 🙂

But seriously. I think there is a difference between divergent views and hostility. F’r instance, it was apparent that Mike Wittmer didn’t merely have differences with Brian’s presentation in A New Kind of Christianity; he was pretty hostile toward Brian, both theologically and personally.

I’m almost certain that this isn’t the case here. While there are doubtless differences between Len and Brian (as the Sweet piece you cite demonstrates), I see them as iron-sharpening-iron differences and not iron-jabbing-your-opponents-eyes-out differences. Both Len and Brian have been accused of various grevious heresies by the self-appointed watchdog ministries; I doubt Len wishes to inflict that pain on anyone else, even if he disagrees with them theologically.

So: Does JM say some different things than ANKoC?

Yes.

Is it possible to enjoy both books?

Yes, I think so, though natural predispositions being what they are, readers might naturally gravitate toward one perspective or the other.

Here’s the fascinating thing, as an aside: Brian in ANKoC and Richard Rohr in The Naked Now (which I’m presently reading) both write out of a conviction that Jesus has become in the hearts and minds of Christians too remote and too ‘divine’ to be of any earthly good, or connection with his followers today. Rohr specifically indicts contemporary Christians of the heresy of gnosticism, saying that while Nicea (or was it Chalcedon? I always forget…) technically settled the matter of Jesus being fully human and fully divine, “most Christians are very good theists who just happened to name their god Jesus.” By contrast, Rohr calls for a robust incarnational ethic, where we disavow a remote ‘theism’ as such and affirm a ‘down and in’ God who is located precisely right here, in our midst. Brian and Rohr both hope that people will stop merely worshiping Jesus and start listening to and following his teachings.

Sweet and Viola, by contrast, are observing an opposite trend: People following the human Jesus, but neglecting the exalted Christ. They wish to reclaim the grandiose language of the Epistles, which speaks of a Christ who fills all-in-all. This is different than a John Piper or Franklin Graham approach of brow-beating the planet earth with a jingoistic Christ, in my opinion.

To begin with, ‘supremacy’ is used in a mystical sense, inspired by T. Austin Sparks. And the divinity of Jesus championed by V&S isparticipatory divinity: We have become partakers of the divine nature through Christ. It’s a perichoretic divinity: The expansion of the dynamic life of the Trinity into communities where this Trinitarian life is made welcome, and thus radiating into the earth. (See Viola’s From Eternity to Here and Sweet’s So Beautiful.) To be honest with you, not counting Rohr, I miss this kind of unbridled mystical-devotional dimension in much of the emerging church. I too agree that everything must change and I don’t share Len’s antipathy with liberation theology (I don’t see how anyone can read Leonardo Boff or James Cone or Gustavo Gutierrez, or know the story and plight of the Base Ecclessial Communities in Latin America, and dismiss liberation theology as simply re-hashed Marxisim), but I will paraphrase anarchist Emma Goldman here: “I don’t want to be part of any Jesus revolution without a perichoretic dance.”

I want to see an emerging conversation that makes room for neo-liberationists and neo-pietists, Jesus Manifesto and Jesus Manifesto. We need neo-pietists in the Conversation to remind us just how revolutionary Paul was, and the Epistles are – that participatory divinity linked to the monotheistic God was truly a new phenomenon in the first century, and can be just as much so today. We need the neo-pietists to remind us of a good, strong, Lutheran-esque Gospel of God’s gratuitous grace and favor toward us, and how we can’t be the ‘hands and feet of Jesus’ unless we’re connected to the authority and animating energies of Christ our Head.

And so: I hope that in the next year, emergents and missionals, organics and liturgicals, conservatives and progressives, can stop writing each other off. If I have to stop calling it the ’emerging’ conversation in order to help missional and neo-pietist folk feel more welcome at the table, I will. Because I think that’s what Jesus – the whole, living Christ – wants.

Devotion, Ethics, & the Tree of Life

treeoflifeiiIn a few days I’ll be speaking at the Transmillennial 2009 conference in Little Rock. I’ll be sharing on The Incredible, Edible God: You Are What You Eat. (or, How Faith & Food go together like Peas & Carrots) – Love feasts! Home gardening! Farmers’ markets! The Tree of Life! What on heaven & earth do all these things have in common? Join Mike Morrell in an interactive conversation on spirituality, hospitality,  culinary pleasure and the coming deep economy.

The Tree of Life has always fascinated me – as a symbol, and icon, a pointer to a deeper reality of divine fellowship and a new way to live. When I heard that Frank Viola was doing a mega-blog-circuit for his latest (and quite possibly greatest) From Eternity to Here today, I just had to ask him about his take on the Tree of Life, which he discusses in Chapter 19, God’s Building Site.

Here’s the interview:

1.) Can you give us a practical example of what it might mean for an individual or fellowship to partake of Christ? Is this a way of describing all spiritual activity a person or church does (ie, worship, prayer, thanksgiving), or do you mean something more particular?

Worship through song, prayer, and any other “spiritual disciplines” or activities can certainly be the vehicle through which a person partakes of Christ. However, an individual can do all of those things without partaking of Him. So it depends on whether or not their inner being is engaged and they are connecting with the Lord through it. For example, in Ephesians 5, Paul exhorts the Asian believers to be filled with the Spirit by singing psalms, hymns, and spiritual songs. Now, one can sing a song and their heart (mind, will, emotions, and conscience) not be engaged at all. In such cases, there will be no “filling.” Or they can sing the same song and be turning to Christ and receiving from the Lord’s Spirit through it, i.e., eating and drinking of His life. It’s the same with reading Scripture. One can read the Scripture in such a way wherein there’s no spiritual transaction at all. Or they can read it as a means of spiritual communion with the living Christ. That said, I think of various spiritual activities simply as utensils. But those utensils are designed to carry food into one’s body. It’s possible to put an empty fork or spoon into one’s mouth. We wouldn’t call that eating.

2.) You outline the superiority of living by eating from the Tree of Life rather than the Tree of Knowledge; you rightly point out that, biblically speaking, the Tree of Knowledge contains knowledge of good as well as knowledge of evil and that the only one who is innate Goodness is the Father. Can you share with us an example of an individual or fellowship who was partaking of the Tree of Life in a way that might have appeared ‘evil’ in the short term but was later vindicated as the highest Good (or Life) in the long-term? I’d love to hear a story from history or your personal experience.

I’m not sure if I can think of a case in my own life where something I did was considered “evil” in the eyes of others, yet I felt it was the Lord. Perhaps writing the book Pagan Christianity falls into that category 😉

Nonetheless, I can think of many cases where a certain action wasn’t understood or thought to have been wrong by others and the Lord’s vindication came later. (At the same time, I can think of times where I completely mistook what the Lord was putting on my heart and interpreted it wrong. Or where I expected Him to do something, and He didn’t.)

I’ll just share one case that comes close to what you’re asking. Once an individual came into our fellowship. For purposes of clarity, we’ll call this person “Pat.” Pat was frustrated because they felt I wasn’t spending enough time with them. Pat then began to sow seeds of discord between myself and a friend of mine. It got so bad that Pat and my friend visited me unannounced and began to rebuke me for all sorts of vague things that Pat had “sensed.” I didn’t say a word. The silence was deafening. I was then rebuked for being silent and not responding to the charges. In a private conversation with my friend sometime afterwards, my friend pressed me about what I really thought of Pat. Feeling forced to give an answer, I said that Pat was not being honest with us about who they were. I perceived that Pat came into our lives under false pretenses and was sowing seeds of discord. My friend defended Pat and asked for concrete evidence. I had none. I just perceived it, and I was certain enough to say it. Not long afterwards, it came out to everyone that Pat had lied about who they were and where they had come from. The story shocked everyone who knew Pat because the details weren’t pretty at all. As soon as we all found out, Pat disappeared.

As to your specific question about something appearing “evil,” some would offer Bonheoffer’s decision to support the plot to kill Hitler as a case in point. Bonheoffer felt it was God who led him to do this, even though he was seriously conflicted over God’s will in doing it.

So there you have it! What do you think, dear readers?

Does God Have An ‘Eternal Purpose’? A Review of From Eternity to Here by Frank Viola

https://i0.wp.com/frometernitytohere.org/pic2.jpgIt was 2003; I was 23. Finally after all these years, I had scraped up the cash (& credit cards) to undergo that great American rite of passage – the summer trip to Europe. Thanks to the generosity of Andrew Jones & family, a couple of house churches, and many other hospitable friends (including Bea & Andy Marshall) I made my way from London to Bournemouth to the Netherlands to Birmingham and Sheffield. While on one leg of my British journey, I was part of a learning party Andrew & friends put on called Wabi-Sabi. It was there I was having a conversation with a fellow American, a new friend 20 years my senior, who had published a book the year before. He was a pastor and church planter, and ‘coach’ to other pastors and church planters. He was asking me what I was up to, & I told him about a book I was working on. (It’s a book I’m still working on! Could this be the month I finish it..?)

“What’s it about?” He asked.

I proceeded to tell him, noting that in part it attempts to unfold “The eternal purpose of God.”

“Well!” He exclaimed jovially but incredulously. “When you figure that one out, be sure to let the rest of us know!”

Ah, these were the early, heady days of postmodern incredulity to metanarratives – even postmodern Christian suspicion of Christian metanarratives. And why not, after all? We (at least, we evangelical Christians) were weaned on a ‘big story’ of “If you were to die tonight, do you have assurance in your heart that you’d go to heaven?” Or, “Have you heard the four spiritual laws?” Those of us following Jesus with awareness of our post-everything cultural shift were keenly aware of the shortcomings of our blithely-uttered “theories of everything,” and were looking for a humbler approach – even if it ultimately meant affirming a much humbler, more localized, cosmology.

But I had a problem – one I still have, at least in part, today. But it’s one I think From Eternity to Here by Frank Viola speaks into. My problem, sitting in Europe circa 2003 – and in the Southeast US of A circa 2009 – is that, since 1998 or so, I was arrested by a grand story – a tale of a God in love, a God who is love, a God who is Community, creating matter and physicality and embodiment as an expression of that love to pour Godself into. If this Story doesn’t do away with the Fall-Rescue-Restoration narrative so common to Christendom, it certainly reframes it, going back further and then permeating the present, to the point (for me at least) that some eschatological tensions are less pronounced. And further still, proponents of this Story have the audacity to believe it’s hiding in plain sight right in our bibles: https://i0.wp.com/jotpuree.com/images/theophanes_in_russia_larger/theophanes_in_russia_larger-Images/16.jpg

Although I am less than the least of all God’s people, this grace was given me: to preach to the Gentiles the unsearchable riches of Christ, and to make plain to everyone the administration of this mystery, which for ages past was kept hidden in God, who created all things. His intent was that now, through the church, the manifold wisdom of God should be made known to the rulers and authorities in the heavenly realms, according to his eternal purpose which he accomplished in Christ Jesus our Lord. (Paul’s letter known as Ephesians, 3:8-11, TNIV – emphasis mine, as ancient Hebrews & Greeks did not have italic fonts yet.)

So this story’s sexy – it has grace, and the overseeing of an age-old ‘mystery,’ in the same sense as ‘mystical’ or Babylonian mystery religion (only better). A message, a power, hidden by God in Christ that would be as revelatory to heavenly principalities and powers as it would be for mere mortals, a divine purpose that’s not only age-old but eternal.

WTF??

By which I mean Where to, Frank?? It is this impenetrable enigma that Viola turns his pen to unfolding for us – and it’s a good thing, too: If folks in the first century CE barely grasped what the apostle Paul (and, Frank contends, Jesus – and others) were talking about, we certainly don’t talk much about this stuff 20+ centuries later.

Except, interestingly, there is a stream of the Christian family who has dared speak about such things: Plymouth Brethren, Christian Missionary Alliance, Keswick Higher Life movement folks, and their descendents. I can’t do justice to their whole story here – that’d be a post in itself, or a series – so I’ll just do a genealogy. Ruth Paxson begat Mary McDonough begat Watchman Nee and T. Austin-Sparks (I’m talkin’ spiritually, now) begat Stephen Kaung and Devern Fromke. Hudson Taylor and AW Tozer run around in this family tree too, somewhere. All of these folks had teaching ministries, or churches, or publishing outreaches, the emphasized the the exchange that happens when those who trust in Christ spiritually ‘die’ with Christ and have his resurrected life take the place of your own – and how this all fits into a larger, more cosmic plan of God’s original purpose – or as Fromke calls it, ‘The Ultimate Intention.’

Frank brings these teachers’ core messages into the 21st century, connecting them in dialogue with other branches of the Christian family, including neo-orthodox folks like Karl Barth & Dietrich Bonhoeffer (who explore radically Christ-centered spirituality as the ground of all being and escape from religion and conventional categories of knowledge), and more recently still post-evangelical luminaries like Stan Grenz and Miroslav Volf who explore the social habits of the Trinity and how these might be reflected in the Church.

So where to, Frank? Frank wants us to begin in the Godhead:

In “the agelessness of eternity,” God had an incredible dream: He wished to expand the “infinite communion” that He had with His beloved Son. He wanted other beings to participate in the interior mystery of the Trinity, to share in the sacred exchange of fellowship, love, and life that flows…between the Father and His Son. He wanted others to participate in “the amiable society” of the Godhead.

But he doesn’t end there. In order to “participate” in the Godhead, the Church in Frank’s depiction lives out four values (see chapter 27):

Communion with God:

As the bride of Christ, the church is called to commune with, love, enthrone, and intimately know the heavenly Bridegroom who indwells her.
Churches that excel in the bridal dimension give time and attention to spiritual fellowship with the Lord. Worship is a priority. Seeking the Lord, loving Him, communing with Him, and encountering Him are central.

Corporate display of the church in an atmosphere of ever-member freedom:

The church is called to gather together regularly to display God’s life through the ministry of every Christian. How? …In open-participatory meetings where every member of the believing priesthood functions, ministers, and expresses the living God in an open-participatory atmosphere (see 1 Cor. 14:26; 1 Pet. 2:5; Heb. 10:24–25, etc).

God dwells in every Christian and can inspire any of us to share something that comes from Him with the church. In the first century, every Christian had both the right and the privilege of speaking to the community. This is the practical expression of the New Testament doctrine of the priesthood all believers.
The open-participatory church meeting was the common gathering of the early church. It’s purpose? To edify the entire church and to display, express, and reveal the Lord through the members of the body to principalities and powers in heavenly places (Eph. 3:8–11).

Community life where practical reconciliation takes place:

The church’s allegiance was exclusively given to the new Caesar, the Lord Jesus, and she lived by His rule. As a result, the response by her pagan neighbors was, “Behold, how they love one another!”

God’s ultimate purpose is to reconcile the universe under the lordship of Jesus Christ (Col. 1:20; Eph. 1:10). As the community of the King, the church stands in the earth as the masterpiece of that reconciliation and the pilot project of the reconciled universe. In the church, therefore, the Jewish-Gentile barrier has been demolished as well as all barriers of race, culture, sex, etc. (Gal. 3:28; Eph. 2:16). The church lives and acts as the new humanity on earth that reflects the community of the Godhead.

Thus when those in the world see a group of Christians from different cultures and races loving one another, caring for one another, meeting one another’s needs, living against the current trends of this world that give allegiance to other gods instead of to the world’s true Lord, Jesus Christ, it is watching the life of the future kingdom lived out on earth in the present. As Stanley Grenz once put it, “The church is the pioneer community. It points toward the future God has in store for His creation.”

It is this “kingdom community” that turned the Roman Empire on its ear. Here was a people who possessed joy, who loved one another deeply, who made decisions by consensus, who handled their own problems, who married each other, who met one another’s financial needs, and who buried one another.

Commission where we love the world as God does:

As we have already seen, when Jesus Christ ascended into heaven, He chose to express Himself through a body to continue His ministry on earth. As the body of Christ, the church not only cares for its own, but it also cares for the world that surrounds it. Just as Jesus did while He was on earth.

The pages of history are filled with stories of how the early Christians took care of the poor, stood for those who suffered injustice, and met the needs of those who were dying by famine or plague. In other words, the early Christian communities cared for their non-Christian neighbors who were suffering.
Not a few times a plague would sweep through a city, and all the pagans left town immediately, leaving their loved ones to die. That included the physicians. But it was the Christians who stayed behind and tended to their needs, sometimes even dying in the process…the early church understood that she was carrying on the earthly ministry of Jesus Christ. She well understood that He was the same today, yesterday, and forever (Heb. 13:8).

So there you have it. I’m still not sure if we contingent humans can dare speak in plain prose about something as ineffable as an “eternal purpose of God.” And yet, if I saw my American church planter friend again today, I’d echo Pete Rollins (or is that Caputo? Or is that Derrida?) in saying that while language definitely fails at such a sublime provocation, we cannot help but speak about eternity and ultimate meaning. Some of the best conversations, orations, letters and books have been penned exploring this very idea, and From Eternity to Here is no exception. What I appreciate about it is its desire to marry the contemplative with the active, the mystical (if you will) with the missional. As I said in my inside-cover endorsement of the book,

Frank Viola is the heir apparent to classic Deeper Christian Life teachers, faithfully bringing their core ideas into the 21st century with his own fresh insight. Visio Dei meets Missio Dei in this passionate examination of what motivates the very heart of God!

Experiencing the Depths of Jesus Christ – Truth In Labeling

https://i0.wp.com/www.jorieken.nl/Marypages/JesusPrayer.jpgSo my friend Frank Viola writes this blog post titled ‘My Problem With Mental Filters,’ and before you know it I’ve written nearly a 1,000-word response before I find out the comments are closed. Alas. Fortunately (thanks to Firefox) my comment was not lost in comment-abyss, so now it’s transmorgifyin’ before thine very eyes into its very own blog-post-a-looza!

You should probably read Frank’s original post first. The upshot: “Mental Filters. They are frustrating. We all have them. Yet we’re unconscious of them.  It makes communication between Christians about spiritual things almost impossible.” Then Frank goes into how little folks understand him when he describes the kinds of ‘organic church’ gatherings that he helps cultivate & experience. So here’s my reply…

Quite true – we all have filters, and they can either help or hinder communication. In fact, I think a wise man once wrote an article called ‘Rethinking Our Theological Conversation Styles.’

That said, did Paul (a comment-er, not the Apostle raised up in some kinda seance or something – what, you think Frank has illicit consultation with dead?? Are you crazy??) really miss the point when he suggests that you, too, have filters? Sure, he pastors what looks like a big church & you’re advocating something quite different which you feel is better…but isn’t that the (your) point? Surely you’re not claiming to have ‘un-filtered’ yourself. Though I suppose you might be claiming, by grace & revelation, to be able to at least temporarily transcend human filtration when lifted into the glorious atmosphere of heaven-come-to-earth that is an organic church gathering.

If so, I’m with Joshua Tucker – please, blog (or podcast) what ‘sharing Christ’ might mean devoid of cliches. Now I know you blogging isn’t going to compare to a live, collective experience of the depths and riches of Christ coming out of many people’s mouths – you’re just the blog-meister here and that’s going to be inherently limited. But it might create, as you say, the hunger to move forward into a real, live experience. Otherwise these allusions without example are just gonna get caught in our filters!

This probably wont’ surprise you, but I take slight issue with something you framed at the beginning of this post. You said that when you tell someone about “the glorious, every member, open participatory, Christ-centered meeting that is under the headship of Jesus by the Holy Spirit,” that people think you’re talking about “…a Quaker meeting…a Plymouth Brethren styled gathering…[or]…old-school charismatic “body ministry” meetings in a home…But none of those kinds of meetings are anything like what I’m speaking about. None can compare…”

Do you think that anything like might be hyperbole? I’ve participated in some of these off-this-planet gatherings you speak of, and I’d say they’re something like the best of Quaker or charismatic body ministry meetings (I’ve been in both of these too) – though I’d probably agree with you that they’re nothing like, say, a megachurch service. 🙂 But let’s give credit where credit is due: Don’t you think that Quakers, or the Brethren, or any number of other such reforming/purifying groups had ideals – and even experiences – like what you’re describing, at the very least in their early days? I don’t think you intend it, but what you’re saying could sound like “Never since the first century has such tangible Christ-centered glory be seen, but now we’re recovering it in our day…” https://i0.wp.com/www.temple.edu/history/UZ/urwin/images/QuakerMeeting_002.jpg

I think the attempt has been made before. And sometimes, successfully.

With that said (sheesh, I didn’t mean to write a feature-length response to your blog! Just goes to show how provocative you are, Frankie), I’m wondering if the “All riches of Christ, all the time” paradigm is sustainable. I don’t wonder this because it seems theoretically unsustainable, but because it’s been un-sustainable in my church’s direct experience. As you know, I was part of a fellowship for many years that had precisely this goal – “all Jesus, all the time.” If you dared bring up theological questions, your aunt Matilda, personal experiences with God, and the like, you were seen as interrupting the very rich flow of the infinite treasures of the Father’s eternal purpose revealed in the Son before time & space.

With a teeny bit of hindsight, I can see two main difficulties with such an approach:

1.) I don’t think we can run with all pistons firing, all the time. Our ‘car’ will flood. Even Paul’s magnificent letters come down to earth and address real people with real problems and a diversity of experiences. Now I totally agree with you, so much of the Church today focuses exclusively on the pieces of the New Testament that focus on behavior and ignore the evocative poetry of a cosmos existing by, through, and within God’s loving embrace via Christ – it’s a real shame. But the minority movements that attempt to correct this by completely inverting the focus do a disservice to the Body. Because…

2.) Not only is it impossible to always be in ‘self-less proclamation mode’ about the glories of Christ, it isn’t actually Christ-like. That is to say, it isn’t particularly loving to encourage members to squelch their spiritual questions or practical needs, nor does it do justice to Christ’s Incarnation, Emmanuel: God. With us. Perhaps Christianity today on a whole is narcissistically focused on the “With us” part of the equation, turning the Gospel into self-help. But attempting to focus on “God” to the exclusion of “With us” does violence to the revelation Jesus brings – that God’s Kingdom has come very, very near, and no detail of our lives is left out.

Please don’t misunderstand me, dear readers-other-than-Frank: Frank has something on his heart that really is substantially different than what many of you have experienced. By all means, you should get a copy of From Eternity to Here in a couple of weeks – it unveils a panoramic portrait of this uber-rich big-picture heartbeat of God that animates Frank’s life & vocation. I’ve spent the last decade of my life pursuing a collective pursuit of God with friends of God meeting in living rooms across the country, because we’ve been captured by just this vision. And it’s real – it’s not a sham. But! Precisely because of my similar passion, I want truth-in-labeling. I’m wary of this vision being over-sold and under-delivered. The next expression of church I end up in will probably be a good deal more…modest, and will emphasize her continuities with the rest of the beautiful, messed-up Christian family more than her discontinuities.

Okay, I’ve said enough here. Overcoming filters, experiencing more of our birthright in Christ – great conversation-starter, Frank!
