Council of Trent: Session XXIV, Reformation, Chapter XXI

CHAPTER XXI. It is declared, that, by certain words used previously, the usual manner of treating business in General Councils is not changed.

The holy Synod,-being desirous that no occasion of doubting may, at any future period, arise out of the decrees which It has published,-in explanation of the words contained in a decree published in the first Session under our most blessed lord, Pius IV., to wit, "which, the legates and presidents proposing, shall to the said holy Synod appear suitable and proper for assuaging the calamities of these times, terminating the controversies concerning religion, restraining deceitful tongues, correcting the abuses of depraved manners, and procuring for the church a true and Christian peace," declares that it was not Its intention, that, by the foregoing words, the usual manner of treating matters in general Councils should be in any respect changed; or that anything new, besides that which has been heretofore established by the sacred canons, or by the form of general Councils, should be added to, or taken from, any one.
