Excerpts from the Council of Trent (1545-1563):
CANON IX.-If any one saith, that by faith alone the impious is justified; in such wise as to mean, that nothing else is required to co-operate in order to the obtaining the grace of Justification, and that it is not in any way necessary, that he be prepared and disposed by the movement of his own will; let him be anathema.
CANON XVI.-If any one saith, that he will for certain, of an absolute and infallible certainty, have that great gift of perseverance unto the end,-unless he have learned this by special revelation; let him be anathema.
CANON XVII.-If any one saith, that the grace of Justification is only attained to by those who are predestined unto life; but that all others who are called, are called indeed, but receive not grace, as being, by the divine power, predestined unto evil; let him be anathema.
CANON XVIII.-If any one saith, that the commandments of God are, even for one that is justified and constituted in grace, impossible to keep; let him be anathema.
CANON XXX.-If any one saith, that, after the grace of Justification has been received, to every penitent sinner the guilt is remitted, and the debt of eternal punishment is blotted out in such wise, that there remains not any debt of temporal punishment to be discharged either in this world, or in the next in Purgatory, before the entrance to the kingdom of heaven can be opened (to him); let him be anathema.
