Reprobation, in Christian theology, is a doctrine which teaches that a person can reject the gospel to a point where God in turn rejects them and curses their conscience. The English word reprobate is from the Latin root probare, which gives the Latin participle reprobatus, the opposite of approbatus. The doctrine is first found in Jeremiah 6:30, but also found in many passages of scripture such as Romans 1:20–28, 2 Corinthians 13:5–6, Proverbs 1:23–33, John 12:37–41, and Hebrews 6:4–8.
