The pure and noble love of husband and wife is a sacred thing. As a priest, I bless it with all my heart. Christian tradition has often seen in Christ's presence at the wedding feast in Cana a proof of the value God places on marriage. “Our Saviour went to the wedding feast," writes St Cyril of Alexandria, “to make holy the origins of human life" .
Marriage is a sacrament that makes one flesh of two bodies. Theology expresses this fact in a striking way when it teaches us that the matter of the sacrament is the bodies of husband and wife. Our Lord sanctifies and blesses the mutual love of husband and wife. He foresees, not only a union of souls, but a union of bodies as well. No Christian, whether or not he is called to the married state, has a right to underestimate the value of marriage.
We have been created by God and endowed with an intelligence which is like a spark of the divine intellect. Together with our free will, another gift of God, it allows us to know and to love. And God has also placed in our body the power to generate, which is a participation in his own creative power. He has wanted to use love to bring new human beings into the world and to increase the body of the Church. Thus, sex is not a shameful thing; it is a divine gift, ordained to life, to love, to fruitfulness.(Christ is passing by, 24)
