Romans 3
Justification: Grace, Faith, and Righteousness — Romans 3:21-26
Paul's argument reaches its climax in Rom 3:21-26, where the righteousness of God is revealed "apart from the law." This answers the indictment he has built since Rom 1:18, where the wrath of God is revealed against all unrighteousness. The problem of 1:18 finds its solution in 3:21. The pivotal phrase is dikaiosyne theou. Cranfield reads the genitive as God's own saving activity, and the Reformers heard in it a righteousness received by faith (Luther made it the article on which the church stands). All sides confess v.26: God is "just and the justifier of the one who has faith in Jesus." The historic question is how the verdict touches the sinner. Trent taught that justification includes an inward renewal, righteousness truly imparted, while the Reformers stressed a righteousness reckoned, or imputed. The 1999 Joint Declaration found a deep consensus beneath the old condemnations: we are accepted by God and renewed by the Spirit, by grace alone through faith. Paul grounds the verdict in the hilasterion of Rom 3:25, echoing the mercy seat of Lev 16:14-15, and draws the pastoral conclusion in Rom 5:1: "we have peace with God."
The Suffering Servant — Isaiah 53
Isa 53:4-6 is the Old Testament's deepest exposition of substitution: "he was pierced for our transgressions... and the LORD has laid on him the iniquity of us all." The Servant suffers not for his own sin but for the people's. Athanasius read the Servant's death as the divine Word bearing what was ours, and Calvin treated Isaiah 53 as the clearest prophecy of penal substitution. The New Testament quotes it more than any other chapter of the prophets. The sin-bearing of 53:6 illuminates the hilasterion of Rom 3:25 and the atoning blood of Lev 16:15. It is fulfilled in the Lamb of God of John 1:29, the one who takes away the sin of the world.
The Day of Atonement — Leviticus 16
Lev 16:14-22 prescribes the Day of Atonement: blood sprinkled on the mercy seat, and a second goat sent into the wilderness bearing the people's iniquities. Propitiation and removal of sin are enacted in one rite. Aquinas read the two goats as together prefiguring Christ's one sacrifice, and Owen drew on this chapter for the nature of substitution. The mercy seat (kapporet) is the meeting place of holiness and mercy. Hebrews makes this the controlling type for Christ's priesthood in Heb 9:11-14, and Paul calls Christ the hilasterion — the mercy seat — in Rom 3:25. The scapegoat's burden anticipates the Servant of Isa 53:6.
