3. From the Council of Trent concerning original sin:

(a) The entire Adam, through the offense of his prevarication, was changed, in body and soul, for the worse. The prevarication of Adam injured not only himself but also his posterity; it transfused not only death and pains of the body into the whole human race but also sin itself, which is the death of the soul (Session 5, numbers 1, 2).

(b) This sin of Adam — which in its origin is one, and being transfused by propagation, not by imitation, is in each one as his or her own — cannot be taken away by any other remedy than the merit of the one and only Savior, our Lord Jesus Christ, who reconciled us to God in his own blood, being made justice, sanctification, and redemption for us (Session 5, number 3).

(c) All human beings had lost their innocence in the prevarication of Adam; they became unclean and by nature children of wrath (Session 6, chapter 1).

19. 2 In fact, in regard to the four theological points just listed, Roman Catholics before the Reformation had exactly the same teachings as Protestants did after it. That is, Catholics had the same teachings regarding the trinity of persons in the Divine, the same teachings regarding original sin, the same teachings regarding the assigning of Christ’s merit, and the same teachings regarding our being justified by believing that we are assigned Christ’s merit; the only difference was that Catholics united that faith to goodwill or good works.
