A thought: what if the angel Gabriel planted the seed but Joseph fertilized it. It would answer a lot of questions I have.  The prophecy says the Saviour will be of the house of David; Joseph is of David’s line NOT Mary. The prophecy says that Jesus was to be born of the Davidic male line, which was and still is held to be a must for Jewish messiahs.  The Hebrew word translated as “virgin”, “Almah”, (עַלְמָה) should always be translated as “a young woman.” This word alone does not teach us anything about her sexual status.  It simply informs us that she is young – not having reached the age of puberty, she was not yet ready for motherhood. As generally interpreted by Jews, “son of man” denotes mankind generally in contrast to deity or godhead, with special reference to their weakness and frailty.  Jesus very often called himself the “Son of Man”. To be truly a Man he must have a human father AND a human mother. Virgin birth mythology was not part of Hebrew tradition or belief – it was pagan. The Assyrian, Babylonians, Egyptian, both Greek and Latin Zoroastrians, etc. are all rift with the traditions of birth among gods and gods and women. In the Bible God does not “father” specific sons of men. God instead makes barren women fertile; this fits the idea of Jesus being born of the young woman Mary from a seed planted by God. Mainstream scholars agree that the nativity of Jesus, if not taken as historically accurate, should be interpreted within the context of first-century Judaism, not in the context of foreign mythologies, which contain only remote similarities. Paul never speaks of the virginal conception. All we learn from him is that Jesus had a Jewish mother. Most important about the Nativity Story is Mary’s response to the Angel;” Here am I, the servant of the Lord; let it be with me according to your word”. Unlike Eve she is completely obedient to God.  That acceptance alone redeems her!
