We have to reconnect with the real Jesus who the canonical Gospels give us . . .but whom we have so misunderstood . . . Yes there is an apologetic task . . . not to prove Jesus’ divinity by some arm twisting fashion . . . But rather we need to speak truly and wisely about Jesus and show that the Gospels, as they are and not as the tradition has shrunk them into being, really do make sense, historical sense. And that the overwhelmingly best explanation for the Christian faith and its rise is that Jesus was and did what the Gospels say he was and did. Otherwise it seems to be that there is the danger [as in Barthian theological circles] of getting to this closed, charmed circle where we don’t allow any natural theology. There is no way to break in. When God has laid his hand on you then the whole system works but you’ve really got no point of contact with the outside world or from outside in.
Gathering from both Craig Keener's response in the CT article (I have not yet read his book) and Darrell Bock's at CT online (see also his blog as well as in the comments in the former post here) I think they aren't that far from McKnight. No one is saying that we should not firmly root Jesus historically for Christian doctrinal re-formation and for apologetics with the wider world. I think the crucial point is for which Jesus do we contend?
