The fact that Mary and Joseph lived a true married life without the normal exchange of marital intimacy only highlights the deepest meaning of chastity. For chastity leads to mature, personal integration.
If God himself paid such respect to the very beginning of human life even before the person was able to respond, so should we. In fact, the more we co-operate with His plan for the creation and salvation of the world, the more we remain open to God who gifts us with the supernatural gift of eternal life and allows us to truly transcend this world.
In a sense, the present situation of every Catholic college or university mirrors the mission of the Church and all her members. Jesus calls us as individuals and as communities of learning to be the light of the world and the salt of the earth.
