John Calvin

Geisler says elsewhere, “Even John Calvin was not an extreme Calvinist on [the atonement], for he believed that by Christ’s death ‘all the sins of the world have been expiated.’ Commenting on the ‘many’ for whom Christ died in Mark 14:24, Calvin said, ‘The word many does not mean a part of the world only, but the whole human race.’ This means that people like Jonathan Edwards, John Gerstner, and R.C. Sproul, who believe in limited atonement, are more extreme than John Calvin! Hence, they have earned the title ‘extreme Calvinists”.

John Calvin 1509-1564
Council of Trent December, 1545- December, 1563
Could the Roman Catechism's comments on "for many" have been at all a reaction to protestant beliefs such as the one expressed by Calvin, above?

Mark 14:24. This is my blood. I have already remarked that, when we are told that the blood is to be shed — according to the narrative of Matthew — FOR THE REMISSION OF SINS, these words direct us to the sacrifice of the death of Christ, without the remembrance of which the Lord’s Supper is never observed in a proper manner. And, indeed, it is impossible for believing souls to be satisfied in any other way than by being assured that God is pacified towards them.

Which is shed for many. By the word many he means not a part of the world only, but the whole human race; for he contrasts many with one; as if he had said, that he will not be the Redeemer of one man only, but will die in order to deliver many from the condemnation of the curse. It must at the same time be observed, however, that by the words for you, as related by Luke — Christ directly addresses the disciples, and exhorts every believer to apply to his own advantage the shedding of blood Therefore, when we approach to the holy table, let us not only remember in general that the world has been redeemed by the blood of Christ, but let every one consider for himself that his own sins have been expiated.
