+ NewAbraham's Faith Counted as Righteousness — Romans 4
Paul proves justification by faith from the Old Testament itself, citing Gen 15:6: "Abraham believed God, and it was counted to him as righteousness." He develops this throughout Rom 4:1-12, arguing that the reckoning came before circumcision, so Abraham is father of believing Jew and Gentile alike. What does this "counting" mean? Wright stresses covenantal-membership language; the Reformers read the imputation of a righteousness received as gift; Trent emphasized that the same grace truly renews the believer. The contrast in 4:4-5 between wages and gift is what all affirm: righteousness is reckoned "to the one who does not work but believes." This Abrahamic promise anchors the covenant of grace traced through Gen 17:7 and reappears in Gal 3:6. Augustine had already insisted that even faith is God's gift, lest grace be owed, a point the Council of Orange made the church's common teaching.
The Virgin Birth — Isaiah 7:14 and Matthew 1
Matt 1:22-23 reads the birth of Jesus as the fulfillment of Isa 7:14: "the virgin shall conceive and bear a son, and they shall call his name Immanuel." Matthew hears in Immanuel, "God with us," the whole meaning of the incarnation. Irenaeus saw the virgin birth as the new beginning of humanity, Mary undoing the knot of Eve. Aquinas defended its fittingness: the new creation requires a new origin. The sign given to faithless Ahaz becomes the sign to the world. The Immanuel theme frames the whole Gospel, returning in Matt 28:20, "I am with you always." It connects to the Word made flesh in John 1:14 and to the protoevangelium's promised seed in Gen 3:15.
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.
Christ Our High Priest — Hebrews 9
Heb 9:11-14 presents Christ entering "the greater and more perfect tent... by means of his own blood, thus securing an eternal redemption." The earthly tabernacle was a copy; Christ ministers in the true sanctuary. Aquinas read Christ's priesthood as the perfect fulfillment of the Levitical types, and Owen built his entire theology of the atonement on Hebrews' priestly logic. The once-for-all sacrifice of 9:26 ends the cycle of repeated offerings. The chapter is a sustained meditation on the Day of Atonement in Lev 16:14-15, and its new-covenant frame fulfills Jer 31:31. The blood that inaugurates the new covenant reappears at the Lord's Supper in 1Cor 11:25.
The Fall and Original Sin — Genesis 3 and Romans 5
Gen 3:1-7 narrates the first disobedience: the serpent's question, the forbidden fruit, and the eyes that are opened to shame. The harmony of creation fractures in a single act. Augustine's reading of original sin became the West's standard: Adam's guilt and corruption pass to all his offspring. He found its warrant in Rom 5:12, "sin came into the world through one man." Aquinas refined it as the loss of original righteousness. The curse of 3:15-19 sets up the whole drama of redemption, and the Adam of this chapter is the representative head whose trespass Rom 5:18 contrasts with Christ's obedience. The fall is answered by the second Adam.
The Protoevangelium — Genesis 3:15
Gen 3:15, the protoevangelium, promises enmity between the serpent and the woman's offspring: "he shall bruise your head, and you shall bruise his heel." In the midst of the curse, the first gospel is spoken. Irenaeus read the seed of the woman as Christ, who recapitulates and reverses Adam's defeat, and Calvin saw here the fountainhead of all covenant promise. The bruised heel anticipates the cross; the crushed head, the resurrection. The promised seed is traced through the Abrahamic covenant of Gen 15:5 and fulfilled in the woman's son of Gal 4:4. The serpent's final defeat is sealed in Rev 12:9.
The Abrahamic Covenant — Genesis 15 and 17
Gen 15:5-6 records the covenant promise and Abraham's response: he "believed the LORD, and he counted it to him as righteousness." In Genesis 15 God alone passes between the pieces, binding himself by oath. Calvin made the Abrahamic covenant the template of the one covenant of grace, and Augustine read the promise as fulfilled in Christ and the church. The sign of circumcision in Gen 17:7-11 seals the promise to Abraham and his offspring. Paul makes Genesis 15:6 the proof text of justification by faith in Rom 4:3 and Gal 3:6. The covenant with Abraham reaches forward to embrace the Gentiles in Christ.
The Binding of Isaac as Type — Genesis 22
Gen 22:9-14 recounts the Akedah: Abraham binds Isaac, raises the knife, and is stopped by the angel; a ram caught in the thicket is offered "instead of his son." "The LORD will provide" becomes the name of the place. Irenaeus and the Fathers read Isaac as a type of Christ, the beloved son carrying the wood of his own sacrifice. Aquinas treated the substituted ram as a figure of the atonement. The mountain of Moriah is traditionally linked to the place of the cross. James cites this scene as the proof of Abraham's living faith in Jas 2:21, and the provided substitute points to the Lamb of God in John 1:29 and the beloved Son of Rom 8:32, whom God 'did not spare.'
The Passover and the Lamb of God — Exodus 12 and John 1:29
Exod 12:21-27 institutes the Passover: a lamb without blemish, its blood on the doorposts, and the LORD passing over the houses so marked. Israel is redeemed by substitutionary blood and a shared meal. Calvin read the Passover as a sacrament of the old covenant, pointing to Christ, and Augustine saw in the lamb a figure of the crucified Lord. John the Baptist names Jesus "the Lamb of God who takes away the sin of the world." The Passover lamb of Exodus is fulfilled in the Lamb of God of John 1:29 and becomes the framework for the Lord's Supper in 1Cor 11:23-26. Paul says plainly, "Christ our Passover lamb has been sacrificed" in 1Cor 5:7.
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.
The Lord's Supper — 1 Corinthians 11:23-26
1Cor 11:23-26 hands on the words of institution: "this is my body... this cup is the new covenant in my blood... do this in remembrance of me." The meal proclaims the Lord's death "until he comes." Aquinas articulated transubstantiation as the mode of Christ's presence, which Calvin rejected in favor of a true spiritual feeding by the Spirit. The Catechism summarizes the Catholic eucharistic faith. The Supper has been the central sacramental dividing line of the church. The "new covenant in my blood" fulfills Jer 31:31 and the Passover of Exod 12:23. The shared loaf expresses the one body of 1Cor 12:12.
The Already and Not Yet Kingdom — Mark 1:15
Jesus' inaugural proclamation in Mark 1:14-15 — "the kingdom of God is at hand; repent and believe" — sets the tension of New Testament eschatology: the kingdom has arrived in him, yet awaits consummation. Wright frames Jesus' whole ministry as the in-breaking of God's reign and the end of exile, while Augustine's City of God distinguished the two cities now intermingled. The parables of Matt 13:31-33 picture a kingdom that grows hiddenly before its harvest. The 'already' is secured by the resurrection of 1Cor 15:20; the 'not yet' awaits the new creation of Rev 21:1. Between them the church lives by hope.
New Heavens and New Earth — Revelation 21
Rev 21:1-5 unveils the consummation: "a new heaven and a new earth... the dwelling place of God is with man... and he will wipe away every tear." Redemption ends not in heaven's escape but in a renewed creation. Augustine's City of God ends with this eternal Sabbath, the vision of God face to face, and Bavinck saw the new earth as creation brought to its destined glory. The covenant formula "God with them" reaches its final fulfillment. The renewed creation answers the first creation of Gen 1:1 and reverses the curse of Gen 3:17. The Immanuel promise of Matt 1:23 becomes eternal fact: God dwells with his people forever.
Pentecost and the Outpoured Spirit — Acts 2
Acts 2:16-21 interprets Pentecost as the fulfillment of Joel: "I will pour out my Spirit on all flesh." The ascended Christ sends the Spirit, and the last days begin with the birth of the church. Augustine preached Pentecost as the love of God poured into the church, the reversal of Babel, and Calvin treated the outpouring as the public inauguration of the Spirit's new-covenant ministry. The Spirit given here is the same who proceeds in John 15. Pentecost fulfills the promise of the Spirit in John 15:26 and the new heart of Ezek 36:27. It constitutes the one body of 1Cor 12:13 and looks ahead to the consummation of Rev 21:3.
