Page "Council of Trent" Paragraph 30

On adjourning, the Council asked the supreme pontiff to ratify all its decrees and definitions.

This petition was complied with by Pope Pius IV, January 26, 1564, in the papal bull, Benedictus Deus, which enjoins strict obedience upon all Catholics and forbids, under pain of excommunication, all unauthorized interpretation, reserving this to the Pope alone and threatens the disobedient with " the indignation of Almighty God and of his blessed apostles, Peter and Paul.

" Pope Pius appointed a commission of cardinals to assist him in interpreting and enforcing the decrees.
