Who was JOHN CALVIN?

Here’s a modest introduction by the one and only Charles Spurgeon:
““Among all those who have been born of women, there has not risen a greater than John Calvin; no age, before him ever produced his equal, and no age afterwards has seen his rival. In theology, he stands alone, shining like a bright fixed star, while other leaders and teachers can only circle round him, at a great distance — as comets go streaming through space — with nothing like his glory or his permanence” . . . “the longer I live the clearer does it appear that John Calvin’s system is the nearest to perfection.””~ Charles Spurgeon
