The Orthodox doctrine of synergy came to its fullest and most refined articulation with the Sixth Œcumenical Synod (680-681). This Synod declared that Christ has both a divine and a human will, and that these two wills co-operated synergistically. This has tremendous ramifications for Christian anthropology. Those who have been organically united to Christ in Holy Baptism (Gal. 3:27) have the Spirit of God living in them; and this Spirit quickens our soul and makes it alive unto God. Our own will then freely co-operates with this newly given Divine Energy which is ever renewed in us through ascetic struggle and participation in the Mystery of His Body and Blood. Thus, the Œcumenical Synods that defined and refined the doctrine of the Person of Christ set forth that, for us who are made in His image, it is not only God’s will that is operative in us (this would be a monoenergistic anthropology – one held by many Reformed Protestants), nor is it our own will working apart from God (this would be Pelagianism), but rather it is the two working together in harmony, neither overwhelming the other (cf. Phil. 2:13-14).” Carmen Fragapane, Salvation by Christ
