Good works and sins differ in their whole kind
Thesis X. Far from counting these and similar works of the godly, done with God's grace and help, among sins, we gladly acknowledge that they are a different kind of thing altogether.
God's law forbids sins, but it commands the works believers do by his grace. Sins displease God and he hates and abhors them; the works of the godly he loves and takes delight in. Sins he punishes severely; good works he rewards out of his goodness. Sins block a person's salvation; good works are among the means of salvation and are the road to it that God has prepared.
Sins do not have God as their author at all, but the corrupt will of the devil and of human beings; good works are to be credited to God and are done as his Spirit moves us. Finally, sins profane and blaspheme God's name, while good works hallow and glorify it.
Latin
X. Tantum abest ut ista, & similia piorum opera, quae per Dei gratiam & auxilium praestant, inter peccata numeremus, ut illa a peccatis toto genere discrepare libenter agnoscamus. Siquidem peccata lege divina prohibentur: Opera vero quae fideles per Dei gratiam faciunt lege praecipiuntur. Peccata Deo displicent, & sunt ipsi odio & abominationi: Opera vero piorum Deus amat, & eis delectatur. Illa Deus severe vindicat: haec vero secundum suam bonitatem remuneratur. Illa obstant hominis saluti: haec vero inter media salutis locum habent, & sunt via ad salutem a Deo praeparata. Illa minime Deum authorem habent, sed pravam voluntatem daemonis & hominis: haec vero sunt Deo ascribenda & fiunt spiritu illius movente. Denique per illa profanatur & blasphematur Dei nomen: per haec vero sanctificatur atque glorificatur.
