“The Genus Apotelesmaticum and the Ancient Church” (Loc. 5962)
Pieper asserts that “The Reformed Confessions, just as also the Reformed theologians, ardently affirm their full agreement with the traditional doctrine of the Ancient Church” (Loc. 5962). They assert the communication of attributes as affirmed in Chalcedon. Yet they do not allow for the two natures of Christ to act together. The divine nature acts only in the divine sphere and the human nature acts only in the human sphere. The ancient Church confessed that God did his divine works through the human nature of Christ without any harm (Loc. 5996).
