Q. 1. How does the Catholic Church define sodomy?
A. 1. I could not find any teaching of the Catholic Church specifically on the matter of sodomy. Although, the Catholic Church is obligated to abide by local laws where sodomy typically includes anal sex, oral sex and bestiality. In some countries, bestiality is excluded.
"Sodomy" finds it origin from the name of the city of "Sodom" in the Holy Bible, Genesis 19:1-11. It relates to the homosexual activities of the men in the city of Sodom. Such activities involved anal and/or oral acts with members of the same gender (male-male).
In some communities, when a person is charged with the offense of "sodomy," it is impossible to know exactly what act was committed, either oral sex, anal sex or bestiality? For that reason, the Criminal Code of each country should be specific in the writing of its laws.
