The Chuch definitely teaches Mary’s Perpetual Virginity as a dogma…
I find it a bit sad that Mary and Joseph’s marriage isn’t the ‘ideal’ marriage as it’s primary end was not procreation… but if it was so, so be it.
I do not believe that Mary being a virgin added anything to her holiness though… she would have been just as perfect if she and Joseph we together in a married way…If I were to venture a guess, it seems to me that this belief came about during a time when the Church believed that something was dirty and sinful about marital relations and that it was better to be a virgin…
That it was a part of God’s plan that Mary and Joseph should have a child, namely the eternal Son of God in human flesh, not by carnal generation but by the supernatural power of the Holy Spirit can hardly be said to make the true marriage of Mary and Joseph less ‘ideal’ than marriages which result in offspring by carnal generation.
Marriage as a sacrament in the Church is a sacred sign of an invisible reality, namely, of Christ’s inseparable union with his body, the Church which is a spiritual union. The marriage of Mary and Joseph which was without carnal sexual relations but which was one of a spiritual union of souls is a perfect sign of Christ’s spiritual union with his bridegroom, the Church.
Sexual relations are not of the essence of marriage. Marriage is entered into by the exchange of the promises between the man and the woman by which they become husband and wife. Sexual relations follow upon the marriage contract. Sexual relations and the procreation of children belong to the second perfection of marriage but not its essential or first perfection which again involves the exchange of the promises between the man and the woman which binds them inseparably to one another in a spiritual union of souls.
It is not unlawful for a man and woman to marry and yet agree together to remain continent or not engage in sexual intercourse as the marriage of Mary and Joseph shows. Indeed, this can be very fruitful which the marriage of Mary and Joseph is the prime example of. In fact, Mary’s virginity was exceedingly more fruitful
than the womb of any other human female for from her virginal womb was the eternal Son of God incarnated and conceived in. Everything about Mary contributed to her holiness and this last fact concerning her infinitely fruitful virginity ought to dispel any notion that Mary’s virginity did not contribute anything to her holiness. I think, godisgood77, that in a certain sense your thinking over these things in a sort of to carnal, fleshly, and earthly a manner when the spirit is more noble than the body and the body is for the spirit and not the other way around. The New Law of Christ is life in the Spirit.
