Grace and free will -- can the unaided will choose the good, or must grace free it first?

Pelagius held that human beings, by their God-given free will and unaided, can choose righteousness and keep the commandments; grace assists but is not strictly necessary, and to deny this is to make God's commands a mockery. Augustine answered that the will, fallen in Adam, is bound to sin until liberated by a grace that goes before and works the very willing of the good, so that salvation is God's gift and not the will's achievement, and the elect are predestined. The church condemned Pelagius and, in time, softened the harder edges of Augustine. The map holds the dispute over where, between the human will and the divine decree of grace, salvation is decided.

Where the field stands

The church condemned Pelagius and followed Augustine: the will is healed by a grace that goes before it. But the predestinarian edge was moderated (the Council of Orange), and the scholastics, above all Aquinas, framed grace and free will as cooperating without competition, the act wholly God's and wholly the human's. The Reformation reopened the wound. No reading is adjudicated here.

    the unaided free will can choose the good -- God commands nothing impossible

    The human will, created free and good by God, retains the inherent capacity to choose righteousness without a special interior grace. God would not command what cannot be done; the commandments themselves prove that the power to obey is given with our nature. Sin is a matter of imitation and habit, not an inherited corruption that binds the will, and moral responsibility presupposes a will genuinely able to go either way. Grace, properly understood, is the gift of free will, the law, and the example of Christ, not a force that works our willing for us.

    lens Pelagius' own writings survive mostly through his opponents; his position is reconstructed from Augustine's replies and the controversy literature.

    the fallen will is bound until grace frees it -- salvation is God's gift, the elect predestined

    The will, fallen in Adam, is in bondage to sin and cannot of itself turn to the good; it must first be freed by grace. Grace is prevenient: it goes before the will and works the very willing, so that even our faith and our good choices are God's gift, lest anyone boast. God's eternal election and predestination of the saved follow, for if salvation began from the human will, it would not be of grace. Free will remains, but as freed by grace, not as the unaided source of its own salvation.

    grace and free will cooperate -- God moves the will without coercing it

    Grace and free will are not rivals but cooperate. God moves the will from within in a way that does not coerce it but perfects it, so that the very freedom of the act is God's gift; the act is wholly God's (as first cause) and wholly the human's (as secondary cause), without competition between them. This synthesis, following the Council of Orange's moderation of Augustine, keeps grace as prevenient and necessary while affirming a real, non-coerced human freedom, against both the Pelagian self-sufficiency and any sheer determinism.

Where the readings diverge

disputes meaning Doctrine / meaning contested
PelagiusvsAugustine of Hippo

Can the unaided human will choose the good, so that moral responsibility and God's just commands are secured (Pelagius), or is the fallen will bound until a prevenient grace frees it and works the willing itself, so that salvation is wholly God's gift and the elect are predestined (Augustine)? The Christian form of the fork between human freedom and the divine decree.

Staged in: Augustine of Hippo; Hwang, Alexander Y., Brian J. Matz & Augustine Casiday (eds.) (2014)

How the debate moved (chronology)
  1. early 5th c. Pelagius — the unaided free will can choose the good -- God commands nothing impossible
  2. early 5th c. Augustine of Hippo — the fallen will is bound until grace frees it -- salvation is God's gift, the elect predestined ↳ responds to Pelagius
  3. 13th c. Thomas Aquinas — grace and free will cooperate -- God moves the will without coercing it ↳ responds to Augustine of Hippo
The open question

If grace works the very willing of the good, in what sense is the willing still ours, and if it remains ours, what has grace added that the Pelagian will lacked?
