A child asked me this question recently especially since we emphasize low cut (in the light of 1Corinth11:14) among males. Incidentally, the pics we show of Jesus in children materials are ones with long hair - and the child brought this to my attention. I did let the child know that I believed (and still do) that Jesus did not keep long hair and that the depictions of Jesus with long hair were not correct. And that's my dilemma - our books depict a long haired Jesus (which is not in line with the aforesaid verse).
I should appreciate your sincere contributions on the topic my good fellows, which I trust would be devoid of acrimony and abuses. A reference to the same topic being exhaustively dealt with in an earlier time would be welcome, if any.
