2 different forgivenesses.
Oh, friend, can you not see you've gone off the rails parsing this? Sin is sin. Forgiven is forgiven.
This is why Catholics recrucify Christ when they take the Mass. Instead of washing to be cleansed, they seek to receive salvation repeatedly.
We are regenerated once, OSAS, and bathed clean at that time. If we sin again, we don’t need to be regenerated, but simply cleansed for those particular sins to continue the spiritual walk.
Penance doesn’t provide that, nor do human good works, only faith alone in Christ alone and confession of those sins so He forgives them immediately and we are returned to our spiritual walk.
