Although the word “purgatory” is not mentioned in the Bible, the reality of purgatory is clearly mentioned there. The words “Trinity” and “incarnation” and “Bible” are not mentioned in the Bible, but these realities are revealed there. Jesus speaks of sins to be forgiven in the life to come (Matthew 12:23). Saint Paul speaks of those saved in the next life “through fire” (1 Corinthians 3:15). Saint Peter speaks of the “spirits in prison” (1 Peter 3:18-20) and of the Gospel “preached to the dead” (1 Peter 4:6). The Bible explicitly tells us to pray for the dead (2 Maccabees 12:44-46). Besides being found in Sacred Tradition, which explicitly affirms the existence of purgatory, it is clearly that the doctrine of it existence is also found in Sacred Scripture.
