Romans 5:1
1Being therefore justified by faith, we have peace with God through our Lord Jesus Christ;
Therefore—on the justification already proved—being justified by faith, we have peace with God through our Lord Jesus Christ. Wesley: this is the sum of the preceding chapters. We have peace with God—being enemies no longer (v. 10), neither fearing his wrath (v. 9). Peace, hope, love, and power over sin are the fruits of justifying faith: where these are not, that faith is not.
Arminian interpreters hear peace as the fruit of those justified by faith. Both camps must say this together first: grace, not works; peace through Christ, not a tranquillity we earn. Faith remains the living condition—enabled by grace, not a meritorious work. Match Romans 3:24 and Titus 3:7: we are justified by his grace as those who believe; the verdict is received by living trust. Do not flatten peace into a feeling that could sit beside an unchanged enmity.
Calvin: when we have obtained righteousness by faith, we have peace with God; this is the peculiar fruit of the righteousness of faith. Those who seek tranquillity of conscience by works labor in vain—either the heart is asleep to God’s judgment, or it is full of trembling and dread, until it reposes on Christ, who is alone our peace. Peace means tranquillity of conscience that feels itself reconciled to God.
Peace is fruit of justification, not a ladder to it. God actually justifies; faith is His instrument, not an independent lever that makes the mercy take. Match Romans 3:24 and Titus 3:7: the whole is from God, and nothing from us. Works cannot buy this quiet; Christ alone is our peace.
Key contrast Both confess justification by faith and peace with God through Christ, grace not works, peace as fruit rather than wage. Arminians hear faith as the graciously enabled condition of those so justified. Calvin’s heirs generally hear God actually justifying, faith His instrument, peace the peculiar fruit of that righteousness.
