The Sixth Commandment pertains to both married and unmarried person. Under Section Two of the Catechism of the Catholic Church regarding the Ten Commandments, paragraph #2353 describes the sin of Fornication, which “is carnal union between an unmarried man and an unmarried woman. It is gravely contrary to the dignity of persons and of human sexuality which is naturally ordered to the good of spouses and the generation and education of children.”
