Do Roman Catholics not read Romans?
23For the wages of sin is death, but the free gift of God is eternal life in Christ Jesus our Lord. Romans 6:23 NASB
Do not Protestants read 1 John?
If anyone sees his brother sinning, if the sin is not deadly, he should pray to God and he will give him life. This is only for those whose sin is not deadly. There is such a thing as deadly sin, about which I do not say that you should pray. All wrongdoing is sin, but there is sin that is not deadly. (1 John 5:16-17)
