Among the many false and misleading claims being made about Jesus' infancy at Debunking Christianity, we read the following comments by Steven Carr:
"After such an auspicious start to his life, why were his family suprised when Jesus started his ministry? Didn't those events give them a little clue that Jesus was special? The answer is that such scepticism is only in Mark, who does not have a birth narrative."
I discussed this issue with Steven two years ago on the TheologyWeb boards. He brought the subject up in a thread on another topic, and when his off-topic objection was refuted, he left the thread. And now, two years later, we see him repeating the same error.
Do the gospels refer to Jesus' family as "surprised"? No. Do the gospels deny that some people, such as His family, viewed Him as "special"? No. For more on this subject, see my recent comments elsewhere. All four gospels, not just Mark, portray Jesus' family as sometimes misunderstanding and opposing Him (Matthew 12:46-50, 13:57, Luke 2:48-50, 8:19-21, John 2:3-4, 7:5), much as His disciples sometimes did. See, further, Eric Svendsen's Who Is My Mother? (Amityville, New York: Calvary Press, 2001). Mark agrees with the other gospels that Jesus' relatives and others opposed Him even after seeing and hearing about some of His miracles, so the opposition can't be a result of their not having heard of anything supernatural about Him. And while Mark doesn't have an infancy account, he does suggest that Jesus was God (Mark 1:3) and that He was a descendant of David (Mark 10:47-48, 11:1-11), for example, in agreement with Matthew and Luke, and he agrees with Matthew and Luke about the presence of anticipation of Jesus' ministry before the ministry began (Mark 1:2-8). The gospel of John apparently was written after the gospels of Matthew and Luke, yet John also decided not to include an infancy account. Mark's choice to do the same doesn't prove that he was unaware of what Matthew and Luke report.
