MORTIFICATION
The practice of Christian asceticism in order to overcome sin and master one's sinful tendencies, and through penance and austerity to strengthen the will in the practice of virtue and grow in the likeness of Christ. Natural mortification is a normal part of self-discipline; supernatural mortification, based on faith, seeks to grow in holiness through merit gained by cooperating with the grace of God. (Etym. Latin mortificatio, a killing, a putting to death.)
