Bits of Calvin on Atonement

Now someone asks, How has Christ abolished sin, banished the separation between us and God, and acquired the righteousness to render God favorable and kindly toward us? To this we can in general reply that he has achieved this for us by the whole course of his obedience …. In short, from the time when he took on the form of a servant, he began to pay the price of liberation in order to redeem us…

This is the wonderful exchange which, out of his measureless benevolence, he has made with us; that, becoming Son of man with us, he has made us sons of God with him; that, by his descent to earth, he has prepared an ascent to heaven for us; that by taking our mortality, he has conferred his immortality upon us ….that, taking the weight of our iniquity upon himself [which oppressed us], he has clothed us with his righteousness.
