Only as much humanity as is consonant with divinity
I've recently been enjoying reading Randal Rauser's Faith Lacking Understanding (a great title, Robin!). In a chapter on the incarnation, while noting the Evangelical tendency to 'elevate Christ's divinity at the expense of his humanity', Rauser references Raymond Brown's memorable words:
'[I]t may well be that most Christians tolerate only as much humanity as they deem consonant with their view of divinity' (172-3 n.4, from Brown's An Introduction to New Testament Christology, 27).
Especially as an evangelical myself, reading that made me chuckle with delight as Brown is onto something! Do give it another read! Evangelical Docetism would thus be rooted in a faulty metaphysic, one that has rejected the significance and goodness of the created order, and its relation to God, leaving only a crass metaphysical dualism divorced from the gracious incarnation of the Word, from God's humanity. I would add, this dualism is one in which Bultmann's project finds as much its home as your average popular evangelical book! As I have often noted before, Bultmann and popular evangelicals are odd, but sometimes nevertheless real, bedfellows. At the base of this common cause is perhaps a similar penchant to tolerate only a limited humanity in their view of divinity (though you wouldn't believe it reading Bultmann's remarks on John 1:14 in his commentary). Brown's words deserve pondering again and again.
Note to self to preach about, sing and pray with the language of the divine initiative in the incarnation of the Logos more often!
