They are embarassed by the story that their sinless miracle-working saviour had himself baptised by John, among a group dunked
So you tell me, but I don't necessarily believe it.
First, I don't really care what embarrases living Christians, according to their non-believing spokespeople, I care what would embarrass a mid-First Century author. We can agree that
John, written near the end of that century, handles things differently than
Mark or Paul.
Second, There are at least three things that lead me to doubt that "Mark" was embarrassed by Jesus' baptism, even assuming that I knew his purpose was to promote belief in Jesus as God, as the Messiah before the Passion, or as always having been sinless, all of which I don't know.
2a. Josephus tells me that John's dunking wasn't for the forgiveness of sins, but came afterwards. There's nothing in
Mark about Jesus doing anything about his sins, or whether he had any sins to do anything about. Later Christians taught that their baptism removed sins, but John didn't teach that his did, so far as we know.
2b. Mark does seem to be interested in the relationship between Jesus and Dunker John. This makes sense if Mark notices that Jesus is conspicuously light in Jews who consider him a contender for the messiahship. Well, except for his own staff, especially that giant of rabbinical scholarhip, Peter. It might be nice to have somebody noteworthy, neutral and without a foreskin on board, at least seeing the potential, while Jesus was actually around to size up.
2c. Either Jesus or John, or both, get quite an earful from on high. It's flashy enough that you, elsewhere, argue that Mark is depicting God adopting Jesus as his son, right then and there. I disagree, but if that is the moment of some unrepeatable and irreversible change (another later Christian idea, one that can't be tied to surviving information about the Dunker), then that would illustrate what the church sells: forgiveness by and reconciliation with God. There's no cause to be concerned with what happened before; all that matters is what happened afterwards. (And of course so little does what comes before matter that
Mark omits it altogether).
Third, the people who compiled the NT (if not all of the authors) apparently believed in the virgin birth. It is simply ludicrous that saying "Our hero's mom skipped the sex thing" increases the credibility of their story with potential converts. Nor is it necessary for their position that God was his biological father. Krishna's birth mother had had several children. So, we need to be skeptical of our own ability to recognize what would be embarrassing (if anything).
Finally, the baptism story, true or false, serves a huge function: it explains why Christians are baptizing people. Baptisms are what the church is trying to encourage people to sign up for. That Jesus was baptized is a crackerjack reason for you to follow suit, if you want Jesus to take a liking to you on judgment day.
"How come Jesus felt he needed to be dunked?' is the kind of question Richard Dawkins would think of, and having thought of it, would think that it poses some crisis for the faithful. Dawkins is not a prime prospect for this sort of thing.
