Reproduction is the natural end of sexual intercourse. It was designed by God for that end. Sex is the means through which spouses share the intimacy and love that Christ shares with his Church. There is nothing sinful in the sexual act between spouses. Reproduction is the result of divine of love. There is nothing wrong with that either.
Our existaence is not a sin. We flow from the hand of God. We are the image and likeness of the invisible God, of his eternal Son. We are sinners, but we are not sin. Sin is an objective reality. Man is not sin. Man commits sins. But that does not take away from his dignity as a son and daughter of God.
Man comes into existence through the Word of God. "And God said . . . " As the Gospel of John tells us, “The Word was made flesh.” Therefore, it follows that if man comes into existence through the eternal Word and the eternal Word assumes our human nature, there is nothing sinful about our nature. Humanity was God’s gift to the Son and the Son was God’s gift to humanity. It is an indivisible relationship of holiness.
Marriage fulfills the mission of Christ to the Church. Marriage is the response to God’s call to love and to serve.
It is heresy to desire to do away with sex, marriage and reproduction. These are God’s gifts and they are goo.
