If God does not do sex before marriage, how do you explain the whole immaculation thing?

God is Spirit; he did not have sex with Mary.

There was no “sex” involved.

Had there been sex, and Mary was not still a virgin, it would have left the parentage of Jesus open up to an earthly father.

In order for Jesus to be born as a perfect human, as an equal in perfection to Adam, there had to be a distinct conception apart from the imperfection we are born with.

This required that no physical contact be between the mother and an earthly father. Obviously this would not have been “normal” had there been a married woman involved in this situation.

And had this been a married woman, then the question of adultery would have come up.

It was foretold in Isaiah that it was to be a virgin who would conceive this child. The Jews who read that prophecy recognized that it would take a miracle of God to have this happen.

They did not, nor do true Christians today put miracles by God in an immoral category.

i think that when you mean God, you mean John Waters.
