Calvinism is kind of a dirty word these days, at least amongst so-called mainline Protestant denominations. They just hate the notion that mankind is not in charge, that God chooses, ultimately, who amongst us will be saved, and who will not.
But then today’s Episcopalians or United Church of Christ are not who I’d ask about salvation. Contra what such modern churches seem to believe, John Calvin is perhaps best known for the absolute sovereignty of God. God is all, God is everywhere, and our theology ought to be about him, and not us.
Throughout the world, all who confess a Reformed faith should acknowledge the debt we owe to Calvin.
