partakes of a share of providence, by being provident both for itself and for others. Wherefore it has a share of the Eternal Reason, whereby it has a natural inclination to its proper act and end: and this participation of the eternal law in the rational creature is called the natural law. Scripture The Genesis creation narratives provide insights into anthropology that inform Catholic theology of sexuality. The following verses are frequently cited in Catholic studies of sexual morality: 1:27: "And God created man to his own image: to the image of God he created him: male and female he created them." 2:21–25: "Then the Lord God cast a deep sleep upon Adam: and when he was fast asleep, he took one of his ribs, and filled up flesh for it.

Jesus comments on these commandments in the Gospel of Matthew:You have heard that it was said to them of old: Thou shalt not commit adultery. But I say to you, that whosoever shall look on a woman to lust after her, hath already committed adultery with her in his heart.Jesus also makes reference to the passages from Genesis in his teachings on marriage in Matthew:Have ye not read, that he who made man from the beginning, Made them male and female?

What therefore God hath joined together, let no man put asunder. They
