Catholic hamartiology

Branch of Catholic thought that studies sin

Catholic hamartiology is a branch of Catholic thought that studies sin. According to the Catholic Church, sin is an "utterance, deed, or desire," caused by concupiscence, that offends God, reason, truth, and conscience. The church believes sin is the greatest evil and has the worst consequences for the sinner, the world, and the Catholic Church itself. Based on the Bible, the Catholic Church distinguishes between two kinds of sins: mortal sin and venial sin. The Catholic Church also distinguishes between the state of being in original sin and the commission of actual sin.
