Calvin comes out swinging here, arguing that indulgences didn’t just drift into error—they grew directly out of a flawed view of satisfaction and ended up turning salvation into a marketplace, where grace was treated as something bought, sold, and distributed by human authority rather than received freely in Christ. He dismantles the idea of a “treasury of merits,” insisting that to supplement Christ’s work with the supposed surplus of saints is not a minor mistake but a direct attack on the sufficiency of the cross, repeatedly grounding his argument in Scripture that points to Christ alone as the one who forgives, cleanses, and redeems. He then brings in voices like Leo and Augustine to show this is not a new objection but a deeply rooted Christian conviction: no martyr’s blood saves, no saint adds to redemption—only Christ does that. Calvin sharpens the critique further by correcting the misuse of passages like Colossians 1:24, arguing that Paul’s sufferings contribute to the building up of the Church, not to the atonement itself, and that confusing the two collapses the gospel into something dangerously distorted. Finally, he exposes the absurdity of trying to “store” or “dispense” grace through papal authority, contrasting it with the gospel itself, where Christ is offered fully and freely to all, not parceled out through documents or payments. The result is a clear, forceful call back to a single foundation: Christ alone is sufficient, and anything that adds to Him ultimately takes away from Him.
