Kerygma · Topic hubs
What Christians believe, in five categories.
Christianity has a creed worth understanding, not just confessing. This hub maps the doctrinal substance of the historic faith across five Kerygma categories — the creedal centre, the ethical perimeter, the visible signs, the spiritual realm, and the hope that closes everything.
The doctrinal arc
Christian belief isn't a flat list. It's a structure. Theology is the centre — God, Christ, the Spirit, salvation. Apologetics defends that centre with reasons. Ethics (the Decalogue and what flows from it) shapes how the believer lives. The sacraments are the visible signs of grace. Eschatology is where the whole thing lands. And the spiritual world — angels, demons, the unseen — runs alongside.
The journey
Stop 01 · The centre
Theology
The doctrine of God, Christology, soteriology, ecclesiology. The disciplines that organise what Christians have always confessed. Start here — everything else is downstream.
Open the Theology category →Stop 02 · The ethical shape
Ten Commandments
Two stone tablets, ten directives, given on Sinai and quoted across both Testaments. The structure of Christian ethics — duties to God, duties to neighbor — and the way Christ and Paul read them.
Open the Ten Commandments category →Stop 03 · The visible signs
Sacraments
Baptism and the Lord's Supper at minimum; confirmation, ordination, marriage, and anointing for traditions that hold seven. The visible signs of invisible grace, with their biblical foundation and theological history.
Open the Sacraments category →Stop 04 · The unseen world
Angels & Demons
Messengers, guardians, principalities — and their dark mirror. The biblical accounts of the spiritual world: the named angels, the fall of the rebels, the encounters across both Testaments.
Open the Angels & Demons category →Stop 05 · The end
Eschatology
"Last things" — death, judgement, the return of Christ, the resurrection, the new creation. The hope that gives the rest of doctrine its direction.
Open the Eschatology category →How to use this hub
This is the hub least suited to Acquainted difficulty — doctrine doesn't live at the surface. Run Conversant if you've sat through catechism or confirmation; Profound if you've worked through serious theology before. The commentary after each answer often does the real teaching.
