Not To Be Confused With
Christian synergism (grace enables and the freed will cooperates) is NOT Pelagianism (the unaided will initiates). The line is whether grace is primary and enabling — which orthodox synergists affirm — or merely a helper to a naturally able will, which is the heresy.
From syn (together) + ergon (work). Held in various forms by Arminian, Wesleyan, Catholic, and Orthodox traditions: God's prevenient grace frees the will, which then truly cooperates. Monergists counter that this makes the decisive difference human; synergists answer that a freed, responsible response is exactly what grace produces.
