Righteousness Through Faith in Christ

The temporal-rhetorical marker "but now" introduces the major positive turn. God's righteousness has been manifested "apart from law," yet the Law and Prophets testify to it. Paul immediately connects this righteousness with dia pisteōs Iēsou Christou. The genitive is famously disputed: it may mean "through faith in Jesus Christ," "through the faithfulness of Jesus Christ," or carry an intentional resonance of both. In every case, Paul adds that it is "for all who believe," emphasizing its universal availability.

All have sinned and lack God's glory, yet are justified freely by grace through the redemption that is in Christ Jesus. Paul describes Christ as hilastērion "through faith, by his blood." Hilastērion can denote a means of atonement or propitiation and is also the Septuagint term for the mercy seat on the ark. Scholars therefore debate whether Paul chiefly evokes sacrificial expiation, divine wrath-bearing, the Day of Atonement sanctuary image, or several overlapping associations.

God's action demonstrates divine righteousness while enabling God to be both just and the justifier of the one who has faith. Consequently boasting is excluded, and justification is said to occur through faith apart from works of law. Because God is one, the same God justifies Jew and Gentile. Paul ends by denying that faith nullifies Torah; rather, "we establish the law," a claim whose precise meaning is developed through the Abraham argument of Romans 4.

Romans 3 brings Paul's opening indictment to its climax and then turns decisively toward the saving action of God. The first section answers objections raised by the argument of Romans 2: Jewish privilege remains real because Israel was entrusted with God's oracles, and human unfaithfulness cannot nullify God's faithfulness. Paul then gathers a chain of scriptural citations to conclude that Jews and Greeks alike are "under sin" and that the law brings knowledge of sin rather than grounds for boasting.

Verse 21 marks the major transition: God's righteousness has now been manifested apart from the law, though attested by the Law and Prophets. Paul presents justification as God's gift through redemption in Christ and describes Christ's death with sacrificial terminology. The chapter closes by excluding boasting and affirming that one God justifies both circumcised and uncircumcised through faith. The argument thus moves from universal accountability to a universally available divine remedy.
