Westminster Confession of Faith
3: Christ, by His obedience and death, did fully discharge the debt of all those that are thus justified, and did make a proper, real and full satisfaction to His Father’s justice in their behalf.[239] Yet, in as much as He was given by the Father for them;[240] and His obedience and satisfaction accepted in their stead;[241] and both, freely, not for any thing in them; their justification is only of free grace;[242] that both the exact justice, and rich grace of God might be glorified in the justification of sinners.[243]
