The Protoevangelium of James

The Gospel of James, also known as the Infancy Gospel of James, the Book of James, and the Protoevangelium of James, is an apocryphal gospel probably written about AD 145, which expands backward in time the infancy stories contained in the Gospels of Matthew and Luke, and presents a narrative concerning the birth and upbringing of Mary herself. It is the oldest source to assert the virginity of Mary not only prior to, but during (and after) the birth of Jesus.
