Although it says only “you shall not commit adultery” why does the sixth commandment forbid all sins against chastity?
Answer
Although the biblical text of the Decalogue reads “you shall not commit adultery” (Exodus 20:14), the Tradition of the Church comprehensively follows the moral teachings of the Old and New Testaments and considers the sixth commandment as encompassing all sins against chastity.
