John Calvin
Christ atoned for my sin, so I do not need to atone myself with "penance" or "self flagellation", or purgatory ...Christ paid the price for my sins
1 John 2:1,2 My dear children, I write this to you so that you will not sin. But if anybody does sin, we have one who speaks to the Father in our defense--Jesus Christ, the Righteous One. He is the atoning sacrifice for our sins, and not only for ours but also for the sins of the whole world.
Congratulations! You agree with the Catholic Church.
That is not a translation. THAT is a paraphrase. I don't even need to crack my Koine NT. HE is the "hilasmos" for our sins.
