Wesley called justification pardon: God, for the sake of the Son’s blood, remits sins and accepts the believer. Arminius, trained in the Reformed schools, could speak of God the Judge absolving a believing sinner “on account of Christ, and of his obedience and righteousness.” The Arminian fork is not a return to merit; it is the claim that this faith is a genuine, enabled response, and that the justified must continue in faith.
“Not by works” in Ephesians 2 and Titus 3 is heard in full. Works do not purchase the verdict. They follow new birth. Where Arminians press is conditionality: God justifies those who believe, and the promise is held out to all who will. Faith is not a work that earns; it is the empty hand—yet a hand that may close or open.
Because grace is resistible, some Arminians (Wesley more clearly than Arminius) teach that a believer may cease to believe and so lose the enjoyment of justification. That is a live internal debate on the Arminian side; it should not be flattened into “they think we earn heaven.”
Calvin’s definition is forensic: God accepts us as righteous by remitting sin and imputing Christ’s righteousness. Turretin refuses to let inherent holiness—though it is as sanctification—enter the justifying sentence as cause or part. The obedience rendered in our name is “reckoned to be truly ours.”
Faith justifies as instrument, not as a virtue that God rewards. It is itself given in effectual calling, so the verdict does not hang on the fragility of our resolve. Union with Christ is the context: we are righteous in another, then made holy in ourselves.
Pastoral Reformed notes stress that this is not a legal fiction. God judges according to truth because the Surety has obeyed and suffered. They also warn against antinomianism: the same grace that justifies also sanctifies. The fork with Arminians is less “faith versus works” than whether the faith that receives the verdict comes from unconditional election and whether the verdict can finally fail.
Key contrast Both camps preach justification by grace through faith on the ground of Christ. Arminians typically treat believing as a resistible, grace-enabled condition that must continue; the Reformed typically treat faith as the instrumental effect of God’s prior, effectual mercy, and the verdict as final for those in Christ.
