One of the reasons I've been turned off by extremely liberal Christians is the fact that they water-down Christian beliefs and turn them into flowery metaphors to the point that their form Christianity is an amorphous, unfalsifiable, and meaningless.
Dr. James McGrath, a fundamentalist-turned-liberal, is a perfect example:
John Loftus praises my doctoral supervisor James Dunn for honestly admitting that Jesus was wrong about the imminent end of the world. Loftus then adds
What I don’t get is how these critically honest scholars could come to these correct conclusions and still profess to be followers of Christ (i.e. Christians). I think anyone with intellectual honesty should jump ship like I have.
The answer is that we've come to realize that, if even Jesus could be wrong, then how much more likely is it that I will be seen with the benefit of hindsight to have been wrong, most likely about a far greater number of things? We've thus found ourselves challenged to let go of yet another fundamentalist assumption we once shared, namely that being a Christian is about Jesus having been right all the time, and following him in the hope that we can be (or at least believe ourselves to be) right all the time. In other words, we understand Christianity to be more about a process, one that involves humbly admitting that we are wrong, rather than about confident claims to certainty.
Common sense would seem to dictate that if God became incarnate, he would not be wrong about when the world would end. Or at least, even if God did not become incarnate, one would think that if Christianity were true then God would not allow the central star of the show, Christ, to be wrong about something like this. Moreover, if Jesus was wrong about this then there is very little, in my view, that separates him from Michael Travesser, the wannabe messiah nut who predicted the end of the world on October 31, 2007.
What Liberals like McGrath have done is to strip Christianity of any meaningful empirical or philosophical implications it may have, and turn it into mere artwork, a lump of clay that may be shaped into anything the believer wants it to be.
