A second-century document that paid special attention to Mary’s virginity was originally known as the Nativity of Mary, but later became known as the Protoevangelium of James.[3][37] The document tells of Mary’s virginity before giving birth, the miraculous way in which she gave birth, and her physical virginity even after giving birth.[38][39][40] The work also claims that Jesus' "brothers" and "sisters"[41] are Joseph’s children from a marriage previous to his union with Mary.[42] However, this text does not explicitly assert Mary's perpetual virginity after the birth of Jesus. https://en.wikipedia.org/wiki/Perpetual_virginity_of_Mary
This is the false writing upon which catholicism has built it's false teaching on Mary.
You, and all catholics, would do well to research it and compare it to the Word. The proto has a lot of errors.
A second-century document ...Heck; the 'document' that Rome assembled; so long ago; shows just how BAD Catholic teaching was in Revelation Chapters 1-3!
Things got better in the SECOND century?
Who knew!!
