(what damage to genuine pastoral theology has been done by making a bogey-word out of the Pauline term synergism, “working together with God”)
I don’t know if Wright has explained this in more depth. But he is right that “synergism” is a term and concept used by the Apostle Paul.
In fact Paul uses sunergos “co-worker” twelve times and sunergeo “work together” three times, and there are respectively one and two other New Testament occurrences of these words. Some of these refer to human co-workers. But in 1 Corinthians 3:9, 2 Corinthians 6:1 and 2 Thessalonians 3:2 a human is a sunergos of God. And even more startlingly, in Romans 8:28, also in the textually doubtful Mark 16:20, we apparently read that God works together (sunergeo) with humans. Compare also Philippians 2:12-13, where the same concept is expressed in different terms.
the view that God and humanity work together, each contributing their part to accomplish salvation in and for the individual. This is the view of salvation found in Arminianism and its theological predecessor Semi-Pelagianism.
(This is by the way a misunderstanding of Arminianism, which does not in general teach that human works have any part in salvation.)
I’m not sure why Wright singles out “pastoral theology”. But certainly “synergism” is being used as a bogey word among Calvinists. And I can only agree that this kind of usage is theologically damaging by the way it is commonly misunderstood as denying the responsibility of Christians, already saved, to do works together with God as he calls us to.
