Bonus: Employing Self-Harm to Humble Oneself

The Middle Ages saw a number of practices that go beyond fasting and waring sackcloth to humble oneself. Self-harm practices sometimes include self-flagellation, wearing a cilice, etc. These rise from a misinterpretation of Paul's statement about training and self-discipline for the games (2 Corinthians 9:26-27), and are not recommended and show a defective understanding of grace.
