Why does the “hypostatic union” matter for atonement theology & Christology?

Sections 4.1–4.6 of the JDDJ have titles like “Human Powerlessness and Sin in Relation to Justification,” “Justification as Forgiveness of Sins and Making Righteous,” “Justification by Faith and through Grace,” “The Justified as Sinner,” “Law and Gospel,” and “Assurance of Salvation.” Taken together, name one kind of question about justification that these subthemes are trying to answer, and why is that question so important?

  • How helpless are we without grace? (4.1) 

  • Does justification only forgive, or also make us new? (4.2) 

  • How do faith, grace, and good works relate? (4.3) 

  • How can a justified person still be called a sinner? (4.4) 

  • What is the place of God’s law and gospel? (4.5) 

  • Can believers have real assurance of salvation? (4.6)

Which atonement model, associated with Anselm, argues that Christ restores God's honor and satisfies divine justice?

300

How does affirming Christ’s full humanity shape the church’s understanding of suffering, solidarity, and pastoral care today?

It assures people that Christ genuinely shares human suffering and truly identifies with human experience.

What is memorialism?

300

According to many traditions (including Wesleyan), justification and sanctification are related in this way.

What is distinct but inseparable?

300

JDDJ §4.4 is titled “The Justified as Sinner.” What central issue is this subtheme trying to address, and why is that issue pastorally and theologically important?

It tackles the question of how someone who is truly justified and renewed by God’s grace can still struggle with sin. The JDDJ says that believers are genuinely made new, yet they do not become sinless; they continually depend on God’s justifying grace. Lutherans describe remaining sin as still present but “ruled,” while Catholics speak of concupiscence that is not sin “in the proper sense.”

This issue matters because it protects both assurance (we really are accepted by God) and humility and vigilance (we still need ongoing repentance and growth), and it helps pastors speak honestly about Christian life without despair or perfectionism.

300

Which atonement view teaches that Christ's self-giving love transforms human hearts and inspires moral change?

Moral influence theory

300

How does Christian teaching on salvation shape ethical living?

400

How does justification provide assurance for believers?

It grounds their confidence in God’s grace rather than in their own achievements

400

What is the main purpose of the JDDJ’s subthemes in §§4.1–4.6 under “Explicating the Common Understanding of Justification”?

They unpack key aspects of justification, such as human inability, forgiveness and renewal, the relation of faith and works, the ongoing presence of sin, law and gospel, and assurance, to show where Lutherans and Catholics now share a common confession and where differences remain, so that their shared understanding of justification can be expressed clearly and responsibly.

400

According to Athanasius and others, how does Christ heal humanity?

By restoring human nature and overcoming the corruption brought by sin

400

How do agreements like the JDDJ support the church’s mission today?

By strengthening unity, credibility, and collective witness to the gospel.

500

Why does studying early Christological heresies matter for theology and ministry today?

Because they clarify why Jesus must be fully divine and fully human for salvation and help the church avoid repeating theological errors.

500

What theological principle expresses why Christ must assume full humanity in order to heal it?

What is not assumed is not redeemed.

(Classic patristic maxim: “What is not assumed is not healed.”; links to assumption soteriology)

500

What does a sacramental worldview affirm about how God interacts with creation?

That God uses ordinary, material things to communicate divine grace.

500

What is one major theological implication of affirming the real presence rather than a purely symbolic view of the Eucharist?

It emphasizes deeper participation in Christ and reinforces the church’s sacramental identity.

500

Why does sanctification matter for the church’s mission today?

Because transformed lives witness to God’s renewing work and embody the gospel.

500

Why is it important for pastors and teachers today to understand the way JDDJ §§4.1–4.6 hold together agreement and difference when explaining justification to a congregation?

Because it helps them present salvation as a coherent, grace-centered reality, avoid old caricatures of “the other side,” and show that real consensus on the heart of the gospel is possible even when nuances differ, strengthening both local teaching about grace and the wider witness of a more united church.

500

Why do many theologians describe atonement as a "kaleidoscope"?

Because no single atonement model fully captures the richness of Christ’s saving work

500

How do Christology, soteriology, and sacramental theology work together to form a unified vision of salvation?

Christ’s identity makes salvation possible, justification and sanctification describe how we receive it, and sacraments embody and sustain it in the life of the church.
