The significance of the individual in such a period of history is that he stands in the midst of the ongoing social movement and gives it guidance and direction.
Such credit must be given to men like Luther and Calvin.
Calvinism (also called the Reformed tradition, Reformed Christianity, Reformed Protestantism, or the Reformed faith) is a major branch of Protestantism that follows the theological tradition and forms of Christian practice of John Calvin and other Reformation-era theologians.
Calvinists broke from the Roman Catholic Church in the 16th century.
The key ideas of the Reformation—a call to purify the church and a belief that the Bible, not tradition, should be the sole source of spiritual authority—were not themselves novel.Calvin lived in Geneva briefly, until anti-Protestant authorities in 1538 forced him to leave.He was invited back again in 1541, and upon his return from Germany, where he had been living, he became an important spiritual and political leader.Even those of us who do not subscribe to many of their views are forced to admit that they stood out as great leaders, notwithstanding their mistakes, in the historical movement which was moving toward individual responsibility and freedom of thought.The reformation was inevitable and certainly we cannot point to any single individual as being responsible for its coming. But in all fairness, we must give some credit to the individual.
