The question was asked, “What is sin?” The short answer is simple, though complicated for and by some due to their emphases on rationalization and subjectivity. Sin is anything that violates the commandments of love: “You shall love the Lord your God with all your heart and with all your soul and with all your strength and with all your mind. And you shall love your neighbor as yourself” (Mk 12:31; Lk 10:27).
