Hell

211. How can we help the souls being purified in purgatory?
1032
Because of the communion of saints, the faithful who are still pilgrims on earth are able to help the souls in purgatory by offering prayers in suffrage for them, especially the Eucharistic sacrifice. They also help them by almsgiving, indulgences, and works of penance.
212. In what does hell consist?
1033-1035
1056-1057
Hell consists in the eternal damnation of those who die in mortal sin through their own free choice. The principal suffering of hell is eternal separation from God in whom alone we can have the life and happiness for which we were created and for which we long. Christ proclaimed this reality with the words, “Depart from me, you cursed, into the eternal fire” (Matthew 25:41).
213. How can one reconcile the existence of hell with the infinite goodness of God?
1036-1037
God, while desiring “all to come to repentance” (2 Peter 3:9), nevertheless has created the human person to be free and responsible; and he respects our decisions. Therefore, it is the human person who freely excludes himself from communion with God if at the moment of death he persists in mortal sin and refuses the merciful love of God.
