The will is not the simple, complete faculty that Pelagius had thought, but it is made up of several if not many conflicting desires. Simply stated, Pelagius had overestimated human nature and its innate ability to desire, think, do or be good, without God's constant help. Pelagianism's Theology of Grace Pelagius, given his assessment of human nature, posits complete autonomy of one's free will before God. Since man is completely autonomous, he is also completely responsible for all his actions, no matter what. That one's free will is completely free and unconditional equals freedom for Pelagians.
Freedom is the central constituent of human nature.
This freedom is a grace which comes from the Grace of God. Freedom does not have a tendency to evil, even after the fall. Thus, if one can will it, they can and must do it. Thus, the human will is totally independent of God in making its moral decisions. Therefore, Pelagian Grace must be merely an external aid, solo ab extra.
