Genesis
+ 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.
Adam and Christ: The Two Heads of Humanity — Romans 5:12-21
Paul's clearest statement of the two representative heads is Rom 5:12-21: "as one trespass led to condemnation for all, so one act of righteousness leads to justification." Death reigned "from Adam," so that all are bound up with him. Augustine built the Western doctrine of original sin on this passage, reading the Latin in quo omnes peccaverunt as "in whom all sinned"; Trent received this, teaching that Adam's sin is transmitted to all and remedied only in Christ. Irenaeus had earlier framed Christ as the new Adam who recapitulates and heals humanity — the Eastern accent on restoration. The two heads structure the whole of redemptive history. The Adam-Christ parallel reaches back to the fall of Gen 3:17-19 and forward to the resurrection harvest of 1Cor 15:22: "as in Adam all die, so in Christ shall all be made alive." Bavinck treats this organic solidarity as the hinge of covenant theology.
Faith and Works in James and Paul — James 2:14-26
Jas 2:14-26 insists that "faith apart from works is dead" and that Abraham was "justified by works when he offered up Isaac." Read flatly against Paul this seems a contradiction; read carefully it is a complement. Calvin distinguished the ground of justification from its evidence: James targets a barren profession, Paul a works-righteousness. Trent read James as showing that living faith, formed by love, is itself part of justification. Both appeal to Gen 15:6, the text Paul cites in Romans 4. The Joint Declaration reframed the old dispute: good works flow from grace as the fruit and sign of justification, not its purchase. James's example of Abraham offering Isaac links to the binding of Isaac in Gen 22:9-12, and his concern for living faith echoes the fruit-bearing of Eph 2:10. The faith that justifies is never alone — it works through love.
The Word Made Flesh — John 1:1-14
John 1:1-14 frames the whole Gospel: "In the beginning was the Word, and the Word was with God, and the Word was God... and the Word became flesh and dwelt among us." The Logos is both distinct from God and fully God. Athanasius made the eternal deity of the Word the linchpin against Arius, a stand vindicated at Nicaea with the term homoousios. Augustine drew on this prologue for his trinitarian theology of the Word. The creational "in the beginning" deliberately echoes Gen 1:1, and the incarnation of 1:14 finds its hymnic parallel in Phil 2:6-7 and Col 1:15-16. The eternal Son enters his own creation.
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.
Why God Became Man — Athanasius on the Incarnation
Athanasius's thesis is famous: the Word became man so that we might be made divine. He reads John 1:14 as the divine remedy for human corruption and death, grounding the whole argument in the creative and re-creative work of the Word. The logic is soteriological: only the Creator can renew the image he made, so only God incarnate can save. Gregory of Nazianzus sharpened the rule — what is not assumed is not healed, and Irenaeus had cast it as recapitulation. This deification theme connects to the image of God in Gen 1:27 and to the glory shared with believers in Rom 8:29-30. Nicaea's homoousios is the grammatical guardrail of the whole vision.
Creation Ex Nihilo — Genesis 1:1-3
Gen 1:1-3 opens Scripture with God creating "the heavens and the earth" by his word: "Let there be light." The church reads this as creation out of nothing — no pre-existing matter constrains the Creator. Augustine wrestled with the nature of time and the 'beginning' itself, and Aquinas defended creation ex nihilo as a truth of reason confirmed by revelation. Irenaeus had already used it against Gnostic emanationism. The creating word of 1:3 is identified in the New Testament with the Logos of John 1:1-3 and the Son of Col 1:16. Creation and redemption share one agent: the Word through whom all things were made.
The Image of God — Genesis 1:26-27
Gen 1:26-27: "Let us make man in our image, after our likeness... male and female he created them." The imago Dei grounds human dignity, dominion, and relationality. Augustine located the image especially in the soul's rational powers, mirroring the Trinity, while Irenaeus distinguished image and likeness, the latter restored by the Spirit. Bavinck argued the whole person, not merely the intellect, bears the image. The plural "let us" has long been read in trinitarian light alongside John 1:26. The image marred at the fall of Gen 3:6-7 is renewed in Christ, the true image of Col 1:15.
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.'
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.
