Council of Trent: Session VI, Justification, Chapter XVI

CHAPTER XVI. On the fruit of Justification, that is, on the merit of good works, and on the nature of that merit.

Before men, therefore, who have been justified in this manner,-whether they have preserved uninterruptedly the grace received, or whether they have recovered it when lost,-are to be set the words of the Apostle: Abound in every good work, knowing that your labour is not in vain in the Lord; for God is not unjust, that he should forget your work, and the love which you have shown in his name; and, do not lose your confidence, which hath a great reward. And, for this cause, life eternal is to be proposed to those working well unto the end, and hoping in God, both as a grace mercifully promised to the sons of God through Jesus Christ, and as a reward which is according to the promise of God Himself, to be faithfully rendered to their good works and merits. For this is that crown of justice which the Apostle declared was, after his fight and course, laid up for him, to be rendered to him by the just judge, and not only to him, but also to all that love his coming. For, whereas Jesus Christ Himself continually infuses his virtue into the said justified,-as the head into the members, and the vine into the branches,-and this virtue always precedes and accompanies and follows their good works, which without it could not in any wise be pleasing and meritorious before God,-we must believe that nothing further is wanting to the justified, to prevent their being accounted to have, by those very works which have been done in God, fully satisfied the divine law according to the state of this life, and to have truly merited eternal life, to be obtained also in its (due) time, if so be, however, that they depart in grace: seeing that Christ, our Saviour, saith: If any one shall drink of the water that I will give him, he shall not thirst for ever; but it shall become in him a fountain of water springing up unto life everlasting. Thus, neither is our own justice established as our own as from ourselves; nor is the justice of God ignored or repudiated: for that justice which is called ours, because that we are justified from its being inherent in us, that same is (the justice) of God, because that it is infused into us of God, through the merit of Christ. Neither is this to be omitted,-that although, in the sacred writings, so much is attributed to good works, that Christ promises, that even he that shall give a drink of cold water to one of his least ones, shall not lose his reward; and the Apostle testifies that, That which is at present momentary and light of our tribulation, worketh for us above measure exceedingly an eternal weight of glory; nevertheless God forbid that a Christian should either trust or glory in himself, and not in the Lord, whose bounty towards all men is so great, that He will have the things which are His own gifts be their merits. And forasmuch as in many things we all offend, each one ought to have before his eyes, as well the severity and judgment, as the mercy and goodness (of God); neither ought any one to judge himself, even though he be not conscious to himself of anything; because the whole life of man is to be examined and judged, not by the judgment of man, but of God, who will bring to light the hidden things of darkness, and will make manifest the counsels of the hearts, and then shall every man have praise from God, who, as it is written, will render to every man according to his works. After this Catholic doctrine on Justification, which whoso receiveth not faithfully and firmly cannot be justified, it hath seemed good to the holy Synod to subjoin these canons, that all may know not only what they ought to hold and follow, but also what to avoid and shun.
