 Near the end of the book, Calvin describes and defends the doctrine of predestination, a doctrine advanced by Augustine in opposition to the teachings of Pelagius.Fellow theologians who followed the Augustinian tradition on this point included Thomas Aquinas and Martin Luther, though Calvin's formulation of the doctrine went further than the tradition that went before him.The principle, in Calvin's words, is that "All are not created on equal terms, but some are preordained to eternal life, others to eternal damnation; and, accordingly, as each has been created for one or other of these ends, we say that he has been predestinated to life or to death."
