Hello
@HosannaHM, I agree with
@Clare73, Roman Catholics mean by their use of the single term "justification" what we Protestants mean by our use of two different terms combined, "justification" and "sanctification". So sadly, a certain amount of confusion often exists in our discussions from the get-go.
The primary difference between us (Catholics/Protestants) boils down to two words that concern how we become righteous, imputation and infusion (just to be clear, both Catholics and Protestants believe that our sins are "imputed" or credited to the Lord Jesus' account for the purpose of atonement, but only Protestants believe that His righteousness, the righteousness of God .. e.g.
2 Corinthians 5:21 is "imputed" or credited to our accounts.
Here are the Justification Canons from the 6th Session of The Council of Trent and the section concerning justification from The Catechism of the Catholic Church, in the two links below (in case anyone cares to read them).
For what it's worth, conservative RC's and conservative Protestants walk in lockstep together where 85-90% of the Christian faith is concerned. IOW, we agree about the Christian faith FAR more than we differ, which is something that we should 'always' keep in mind. That said, I do not believe that it's possible to truly harmonize certain parts of the faith that we disagree on, unless one side concedes, that is (and I don't see that happening anytime soon
).
