I am, and have always been, Jewish, but I was raised in a household with a father who was secularly Christian. We “celebrated” Christmas and Easter, but never went to church. We put up a tree but did not speak of Jesus. We colored eggs but did not discuss resurrections.
I was recently asked by someone I very much respect to address "the" question. So I started to write the answer in a post... about five times without any luck. The "Why does a 20-something join a Reform Congregation" question.
