Instruction of the Faithful

15. This will sufficiently inform the people on the subject of indulgences. But since special pains must be taken to ensure that the faithful do seek indulgences, the clergy should provide further instruction. With Apostolic zeal they should attack in their preaching the vices of the age which flourish everywhere, remembering the words of Isaiah 58: "Cry out; do not stop. Raise up your voice as a trumpet and announce their crimes to My people, their sins to the house of Jacob". Let them proclaim the need for penance and insist on the inevitable loss of the soul unless sins are destroyed by means of repentance, as is conveyed in the saying of Christ the Lord, Luke 13: "Unless you do penance, you will all likewise perish". In addition, let them extol the riches of God's mercy which are poured out for those who completely cast off their former evil ways and provide themselves with a new heart and a new spirit. All the while they should be aware of the Lord's words in Ezekiel 18: "Be converted and do penance for all your iniquities, and you shall not be destroyed by iniquity. Cast from you all your prevarications and make yourselves a new heart and a new spirit.... For I do not wish for the death of the one who is dying, says the Lord God, turn again and live". And in chapter 33: "As I live, says the Lord God, I do not wish for the death of the sinner, but rather that the sinner be converted from his way and live".
