John Paul II, January 28, 1988
Mary was therefore a virgin before the birth of Jesus and she remained
a virgin in giving birth and after the birth. This is the truth presented by
the New Testament texts, and which was expressed both by the Fifth
Ecumenical Council at Constantinople in 553, which speaks of Mary as
'ever virgin', and also by the Lateran Council in 649, which teaches that
the mother of God...Mary...conceived [her Son] through the power of the
Holy Spirit without human intervention, and in giving birth to him, her
virginity remained incorrupted, and even after the birth her virginity
remained intact.
