Calvin and the Calvinists

Many have taken it for granted that the Calvinistic theology which spread across the western world in the seventeenth century was substantially the theology of John Calvin himself. it was a considerable surprise therefore when Dr. R. T. Kendall attempted to show, in his Calvin and English Calvinism to 1649, published in 1981, that later Calvinism was in fact a departure from the theology of the Reformer.
