The final session of the Council of Trent concluding on this day in 1563, the ecumenical session convened by Pope Paul III in response to the spreading Reformation-movement, with decrees issued before the last adjournment (under Julian III) addressing the rather heady topics of the cult of saints, relics, icons and the indulgences that sparked the revolt of
Martin Luther in the first place. With the papal bull,
Benedictus Deus, the decrees, definitions, dogma and scope of duties—including the
Librorum Prohibitorum from a prior round—were ratified by Pius IV the following
January.
