From the first moment of her existence, the Virgin Mary was preserved free from all sin and all tendency towards sin. Yet, the Immaculate Conception of the Virgin Mary was miraculous, not only in that she was preserved free from all sin, but also in the manner by which her Immaculate Conception occurred. God desired that the Virginity of Mary, the Mother of Jesus Christ, be so perfect, complete, and all-encompassing that even the manner of her Immaculate Conception was required by God to be entirely Virginal, occurring solely and entirely by a miracle of God and not in the usual way. Therefore, solely by means of a most wonderful and singular miracle of God, the Virgin Mary was conceived of both her parents, Saint Joachim and Saint Ann, without sexual union and within their complete purity of body, heart, mind, and soul. This teaching is trustworthy and true; it cannot be otherwise.
It is a part of the total and constant Virginity of Mary, the Mother of God, that even the manner of her Immaculate Conception was completely Virginal, occurring solely and entirely by means of a miracle from the Mercy of God, and not by means of human will or action. Saint Joachim and Saint Ann did not conceive the Virgin Mary by means of marital relations. The Immaculate Virgin Conception of the Virgin Mary occurred in a manner which was wholly virginal and wholly miraculous. Such a true virgin conception could never be brought about by nature or science or human intervention, but solely by a miracle of God. Even so, by the power of God, the body of the Virgin Mary came from both her father, Saint Joachim, and her mother, Saint Ann. The Virgin Mary has as her immediate ancestors both Saint Joachim and Saint Ann. Saint Joachim is the Virgin Mary’s real biological father and Saint Ann is the Virgin Mary’s real biological mother, yet the Immaculate Conception of the Virgin Mary occurred solely by means of a miracle of God. This teaching is true and worthy of full acceptance by all Christians.
To those who doubt this teaching, I say, “Which is more virginal, to be conceived with sexual union, or to be conceived without and solely by a miracle of God?” The answer must be that it is more virginal to be conceived without sexual relations, by an act of God rather than by a human act. So then, do you really believe that the ever-Virgin Mary is less virginal than she could be? On the contrary, Mary could not be any more a Virgin than she is, for God willed that the Mother of God be perfect in every way. Therefore, and without any doubt, the perfect-Virgin Mary was conceived solely by a miracle of God and born solely by a miracle of God. Otherwise, she would not be the perfect Virgin that she is.
The Virginity of Mary, the Mother of the Messiah, is without flaw, omission, or imperfection.
