|LUTHER||COUNCIL OF TRENT|
|Sin is really sin, regardless of whether you commit it before or after you have come to know Christ. And God hates the sin; in fact, so far as the substance of the deed is concerned, every sin is mortal. It is not mortal for the believer; but this is on account of Christ the Propitiator, who expiated it by His death. As for the person who does not believe in Christ, not only are all his sins mortal, but even his good works are sins, in accordance with the statement (Rom 14:23): ‘Whatever does not proceed from faith is sin.’ Therefore it is a pernicious error when the sophists distinguish among sins on the basis of the substance of the deed rather than on the basis of the persons. A believer’s sin is the same sin and sin just as great as that of the unbeliever. To the believer, however, it is forgiven and not imputed, while to the unbeliever it is retained and imputed. To the former it is venial; to the latter mortal. This is not because of a difference between the sins, as though the believer’s sin were smaller and the unbeliever’s larger, but because of a difference between the persons. For the believer knows that his sin is forgiven him on account of Christ, who expiated it by His death. Even though he has sin and commits sin, he remains godly. On the other hand, when the unbeliever commits sin, he remains ungodly. This is the wisdom and the comfort of those who are truly godly, that even if they have sins and commit sins, they know that because of their faith in Christ these are not imputed to them.
Thus we abide in a humility that is not fictitious or monastic but authentic, because of the filth and the faults that cling to our flesh; if God wanted to judge severely, we would deserve eternal punishment on account of these.
|If any one denies, that, by the grace of our Lord Jesus Christ, which is conferred in baptism, the guilt of original sin is remitted; or even asserts that the whole of that which has the true and proper nature of sin is not taken away; but says that it is only rased, or not imputed; let him be anathema. For, in those who are born again, there is nothing that God hates; because, There is no condemnation to those who are truly buried together with Christ by baptism into death; who walk not according to the flesh, but, putting off the old man, and putting on the new who is created according to God, are made innocent, immaculate, pure, harmless, and beloved of God, heirs indeed of God, but joint heirs with Christ; so that there is nothing whatever to retard their entrance into heaven. But this holy synod confesses and is sensible, that in the baptized there remains concupiscence, or an incentive (to sin); which, whereas it is left for our exercise, cannot injure those who consent not, but resist manfully by the grace of Jesus Christ; yea, he who shall have striven lawfully shall be crowned. This concupiscence, which the apostle sometimes calls sin, the holy Synod declares that the Catholic Church has never understood it to be called sin, as being truly and properly sin in those born again, but because it is of sin, and inclines to sin. TRENT, SESSION V, CANON 5.
If anyone says that in every good work the just man sins at least venially, or, what is more intolerable, mortally, and hence merits eternal punishment, and that he is not damned for this reason only, because God does not impute these works into damnation, let him be anathema.
