The reformers Luther and Calvin did not wish to break from the early church, but to reform the church of their day to make it truly evangelical and historic. Both agreed that the church of the first five hundred years had succeeded in maintaining the essential substance of New Testament Christianity. . . . A return to the historic church, to the great fathers of the first five centuries, is . . . to develop into biblically and historically informed adulthood.
