Conception is the beginning of human life, and the unborn child is a living human being. Abortion violates the sanctity of life and is thus mala in se violation of God’s creation. Abortion is sin and always unjustified and always unexcused. CCC rebuffs any teaching that abortion due to rape, incest, birth defects, gender selection, birth or population control, or the physical or mental well-being of the mother are acceptable.

Human Sexuality and Marriage:
God stipulates that the only legitimate marriage is the joining of one man and one woman. His gift of sexual intimacy is to be celebrated only within the bond of legitimate marriage, and any form of sexual behavior outside of legitimate marriage including but not limited to fornication, adultery, homosexuality, bisexuality, bestiality, incest, and pornography are sinful perversions of God’s gift. Additionally, God disapproves of and forbids any alteration of one’s gender by surgery or appearance.
