How Should We Understand Intercourse within Marriage If the Church Says Mary Remained “Undefiled”; Isn’t Consummation Necessary?


I have always regarded faithfulness within marriage as a path to holiness equal in virtue to that of priests or sisters who remain celibate. However, with statements like "And to holy Mary, [the title] ‘Virgin’ is invariably added, for that holy woman remains undefiled" (Medicine Chest Against All Heresies 78:6 [A.D. 375]), the Church seems to teach that intercourse defiles the body. How can I reconcile the fact that a marriage is not considered valid unless it is consummated with the teaching that Mary never had intercourse with Joseph?


The Church does not teach that intercourse within marriage defiles the body. In Christian marriage such physical union is a holy thing. That quote expressing Mary’s perpetual virginity used a poor choice of words. Even though a marriage is consummated on the marriage bed, it is indeed valid the moment the vows have been spoken at the altar. The vows of religious life comprise an act of worship that direct the person to God in a more immediate way than do the vows of marriage. The process is considered higher because of its greater proximity to God. But the goals of both religious life and marriage are the same: union with God for all eternity. I encourage you to get the book Good News About Sex and Marriage by Christopher West.
