Catholic moral theology is a type of Christian teaching that looks at how we should live our lives in a way that is pleasing to God. It teaches us about what is right and wrong and how we can make sure that we make decisions that are in line with God's will. In Catholic moral theology, we learn about the 10 Commandments, which are 10 rules that God gave us to make sure that we live good and righteous lives. Catholic moral theology also teaches us to look closely at our conscience, or our inner sense of what is morally right and wrong, and to make sure that our choices reflect our conscience and align with God's law.
