Making restitution for sins is obscene?
Saying someone will burn in Purgatory for a sin God has forgiven him is obscene. It means either God doesn’t know how to forgive, or He only forgives part-way.
The idea that if you do XYZ, God will fully forgive you means we can exchange good works for bad - the accounting approach to acceptance by God, which is in violation of practically every page of scripture.
While we are saved to do good works, no good works can save us. Making restitution to humans after forgiveness from God is fine. Making restitution to God for forgiveness is not.
“4But God, being rich in mercy, because of the great love with which he loved us, 5even when we were dead in our trespasses, made us alive together with Christ— by grace you have been saved— 6and raised us up with him and seated us with him in the heavenly places in Christ Jesus, 7so that in the coming ages he might show the immeasurable riches of his grace in kindness toward us in Christ Jesus. 8For by grace you have been saved through faith. And this is not your own doing; it is the gift of God, 9 not a result of works, so that no one may boast. 10For we are his workmanship, created in Christ Jesus for good works, which God prepared beforehand, that we should walk in them.” - Ephesians 2
Please notice the verb tenses in verse 6: raised us up with him and seated us with him in the heavenly places in Christ Jesus.
Jesus made restitution for our sins. That’s ALL that’s needed.
