So you're going on record now and stating the first Marian dogma of for all Protestants where She was a literal Virgin when She Conceived?
Virgin Birth, yes
The Miraculous Virginity of Mother Mary was special and Her Ever Virgin title reflects that. You know it, I know it and She Knew it.
She knows it, and uses the Magnificat reminiscent of Hannah to express it.
All the rest is more reminiscent of pagan myth and Gnosticism than who she was, or what apostolic teaching is.
False unsubstantiated Dogma outside of all Scripture and apostolic tradition. The only documented support comes indirectly from PofJ and similar pseudoepigraphic writings.
PoJ references Matthew and Luke for his information.
Matthew was written after the 62Ad date in which tradition has James dying.
It is a work of fiction, contradicts Scripture, and contradicts the human nature of Jesus.
