So where did you get a seminary degree that does not include some training in logic? Can a woman be the physical mother of someone who pre-existed her?
Irrelevant. Christianity is in question here. The teachings are in question.
Can a woman be the physical mother of someone who pre-existed her?
Yes, the only person I know where this is so is Mary. This is because God does not exist in time. So saying that He existed before Mary conceived Him is inaccurate. Time has no meaning to the God who created all of the beginning and ending of creation in a single act. Once again, the Motherhood of Mary does not make her the sole author of the existence of Jesus. Motherhood does not imply sole authorship to begin with.
Only if God wants it that way.....do you have a problem with that??
