Kerygma · Doctrine & Theology
Theology trivia, with the doctrine sourced.
The disciplines that organise what Christians have always confessed — Trinity, Christology, soteriology, ecclesiology — and the verses each rests on. Kerygma's Theology category tests the structure of the faith, not just its surface.
What's covered
- The doctrine of God — divine attributes, the Trinity, the names of God.
- Christology — the person and natures of Christ, the hypostatic union, the work of Christ.
- Pneumatology — the Holy Spirit, Pentecost, the gifts.
- Soteriology — sin, grace, justification, sanctification.
- Ecclesiology — the church, marks, sacraments, ministry.
- The creeds — Apostles', Nicene, Athanasian. Why they say what they say.

Sample question
Which ecumenical council formally affirmed that Christ is "fully God and fully man" in two natures?
"And the Word became flesh and dwelt among us, and we have seen his glory, glory as of the only Son from the Father, full of grace and truth."John 1:14
Chalcedon (AD 451) is the council that produced the formula: Christ is "in two natures, without confusion, without change, without division, without separation." Nicaea earlier affirmed his full divinity against Arius; Chalcedon clarified his full humanity and how the two natures relate. Most Christian traditions today still hold this definition as the orthodox boundary on Christology.
