This noun describes the act of putting off or removing something, particularly like removing clothing. Colossians 2:11 uses it metaphorically for spiritual circumcision: 'in the putting off of the body of flesh, by the circumcision of Christ.' Just as physical circumcision removes a piece of flesh, Christian circumcision—accomplished at conversion—involves putting off the old sinful nature. The imagery combines undressing (removing garments) with surgical removal (cutting away flesh). The term emphasizes complete divestment, not partial reform.
