In part, the
Protoevangelium of James, which while not admitted to the canon of scripture, was not banned from Christian lore. It is generally dated around 150AD.
In part, the Gospel of Luke, Chapter 1. Which dates to between 60 and 100 AD.
In part, the
Gospel of the Nativity of Mary, chapter three. Date unknown. Accordingly thy wife Anna will bring forth a daughter to thee, and thou shalt call her name Mary: she shall be, as you have vowed, consecrated to the Lord from her infancy, and she shall be filled with the Holy Spirit, even from her mother’s womb. She shall neither eat nor drink any unclean thing, nor shall she spend her life among the crowds of the people without, but in the temple of the Lord, that it may not be possible either to say, or so much as to suspect, any evil concerning her. Therefore, when she has grown up, just as she herself shall be miraculously born of a barren woman, so in an incomparable manner she, a virgin, shall bring forth the Son of the Most High, who shall be called Jesus, and who, according to the etymology of His name, shall be the Saviour of all nations.
In part, holy tradition from the 1st Century.
Note that neither the protevangellium nor the Gospel of the Nativity of Mary are scripture, but neither were proscribed, either. So both bear witness to the early Tradition of Mary’s grace-filled birth.
