"Contemporary Christianity, diverse and complex as we find it, actually may show more unanimity than the Christian churches of the first and second centuries. For nearly all Christians since that time, Catholics, Protestants, or Orthodox, have shared three basic premises. First, they accept the canon of the New Testament; second, they confess the apostolic creed; and third, they affirm specific forms of church institution. But every one of these -- the canon of Scripture, the creed, and the institutional structure -- emerged in its present form only toward the end of the second century."
