A) Jesus was 100% mortal. That's the central point of Christianity.
B) Priests could marry until the middle ages. They still can in the Greek Church, which has the same New Testament as the Roman one.
C) These stories were in existence well before the Church itself had any wealth or power to protect. The point has been made in the past that priestly celibacy was designed to protect the Church's assets, denying legitimacy to the offspring of its officials, and there is reason to this. However, the Gospels predate that reason. Jesus may have been many things. He was not married. It makes no sense.
