The Gospel of Philip
“Some said, ‘Mary conceived by the Holy Spirit.’  They are in error.  They do not know what they are saying.  When did a woman ever conceive by a woman?  Mary is the virgin whom no power defiled.  She is a great anathema to the Hebrews, who are the apostles and the apostolic men.… And the Lord would not have said ‘My Father who is in heaven’ unless he had had another father, but he would have said simply ‘my father.’” – 55.23-36
