Quotes from Chafer: SANS PAUL -- A clear recognition of that which, through divine grace, the Church is, of the supreme position she occupies as the Body of Christ, and of the glory and exaltation which awaits her as the Bride of the Lamb, is indispensable if a worthy perspective of God's plan and purpose is to be gained. The all but universal disregard on the part of theologians for the Pauline revelation respecting the Church has wrought confusion and damage to an immeasurable degree.
APOCRYPHAL COVENANTS -- The essential error of Covenant Theology is mentioned at this point only as it bears on human responsibility before God. The theological terms, Covenant of Works and Covenant of Grace, do not occur in Scripture. If they are to be sustained it must be wholly apart from Biblical authority.
What is known as Covenant Theology builds its structure on these two covenants and is, at least, a recognition--though inadequate--of the truth that the creature has responsibility toward his Creator. Covenant Theology has Cocceius (1603-1669) as its chief exponent. He taught that before the Fall, as much as after it, the relation between God and man was a covenant. The first was a Covenant of Works. For this was substituted, after the Fall, the Covenant of Grace.
