Unless Jesus was Josephs' son, then your entire faith is based on adultery.

God (Yahweh) has a wife, her name is Asherah and she has been carefully cut from most of the Bible, even though statues of her still stood in the Temple in Jesus' time. Mary was married or at least promised to Joseph.

If Yahweh impregnated Mary, then he is no better than philandering Zeus.
