Every human being is called to receive a gift of divine sonship, to become a child of God by grace. However, to receive this gift, we must reject sin, including homosexual behavior—that is, acts intended to arouse or stimulate a sexual response regarding a person of the same sex. The Catholic Church teaches that such acts are always violations of divine and natural law.
Some argue that neither the Bible nor apostolic tradition condemns the practice of homosexuality. Passages such as Leviticus 18:22–30, Romans 1:26–27, 1 Corinthians 6:9, and Jude 7 serve as ample proof that Scripture indeed condemns homosexuality. Below is ample proof from tradition. The Fathers are especially harsh against the practice of pederasty, the homosexual corruption of boys by men.
Christians have always condemned contraceptive sex. Both forms mentioned in the Bible, coitus interruptus and sterilization, are condemned without exception (Gen. 38:9–10, Deut. 23:1). The early Fathers recognized that the purpose of sexual intercourse in natural law is procreation; contraceptive sex, which deliberately blocks that purpose, is a violation of natural law.
In 1968, Pope Paul VI issued his landmark encyclical letter Humanae Vitae (Latin, "Human Life"), which reemphasized the Church’s constant teaching that it is always intrinsically wrong to use contraception to prevent new human beings from coming into existence.
The Catholic Church has always condemned abortion as a grave evil. Christian writers from the first-century author of the Didache to Pope John Paul II in his encyclical Evangelium Vitae ("The Gospel of Life") have maintained that the Bible forbids abortion, just as it forbids murder. This tract will provide some examples of this consistent witness from the writings of the Fathers of the Church.
