The Perpetual Virginity of Blessed Mary

²¹ But as we do not deny what is written, so we do reject what is not written. We believe that God was born of the Virgin, because we read it. That Mary was married after she brought forth, we do not believe, because we do not read it. Nor do we say this to condemn marriage, for virginity itself is the fruit of marriage; but because when we are dealing with saints we must not judge rashly. If we adopt possibility as the standard of judgment, we might maintain that Joseph had several wives because Abraham had, and so had Jacob, and that the Lord's brethren were the issue of those wives, an invention which some hold with a rashness which springs from audacity not from piety. You say that Mary did not continue a virgin: I claim still more, that Joseph himself on account of Mary was a virgin, so that from a virgin wedlock a virgin son was born. For if as a holy man he does not come under the imputation of fornication, and it is nowhere written that he had another wife, but was the guardian of Mary whom he was supposed to have to wife rather than her husband, the conclusion is that he who was thought worthy to be called father of the Lord, remained a virgin.
