- Lateran Council, Oct, 649, DS 503:
“If anyone does not in accord with the Holy Fathers acknowledge the holy and ever virgin and immaculate Mary was really and truly the Mother of God, inasmuch as she, in the fullness of time, and without seed, conceived by the Holy Spirit, God in the Word Himself, who before all time was born of God the Father, and without loss of integrity brought Him forth, and after His birth preserved her virginity inviolate, let him be condemned.”
COMMENT: It is important to note the word integrity, which means the state of being untouched, and so is a physical word. It rules out lesions, blood and similar things. The Greek text, which is of equal authority, has “aphthoros,” without corruption.
It was not a General Council, but the Pope was present and approving, hence the teaching under anathema makes it equivalent to that of a general council. There was further approval by Vatican II, as we shall see, in LG 57, which repeated the word “integrity,” and gave a note referring us to this text of Lateran I. John Paul II in a General Audience of Jan 28, 1987 cited this text: “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.’”
