How can I expiate the sins of the tongue, of the flesh, sin in thoughts and every other sin? As far as I understand when we sin and go to Confession we are in state of grace again but our soul is stained by the sins we have committed and we have to make reparation for them…no one ever told me how to do it? What prayers do I have to pray or what else I need to do?
You really can’t, not in the total sense, anyway. That is why Christ died for us on the cross. Not to trivialize the Passion with a slang expression, but He did the “heavy lifting”. If He hadn’t done what He did, you could
never make reparation for your sins.
But He did. All that God asks of us, is to do what we can, penances, prayer, and sacrifice, to
“fill up those things that are wanting of the sufferings of Christ” (Colossians 1:24 DRV), and He offers us through the Church the grace of plenary and partial indulgences. Accept God’s gift and try to become as holy as you can be. That’s all you can do, and that’s all that’s expected. Beyond that, don’t worry about it.
I would truly like to see PBEs (Protestants/Baptists/evangelicals) explain this verse of Scripture and how it doesn’t conflict with their
credo of “Jesus did it all”, how it doesn’t imply that we have something to do, ourselves, to atone for our sins — prayer, penance, reparation, sacrifice, offering of our sufferings.
The closest thing I can see, is that they do accept the Scriptural mandate of fasting, but only as a spiritual discipline, not as a means of penance and reparation. As an evangelical friend of mine once told me, they do not view our mitigated fasting as “real fasting” — he said “that’s not a fast, that’s a diet”. (I assume that, if nothing else, he at least drank water, I would hope so anyway.) He told me there is power in fasting, and on this point, I agree with him.
