Topics
Every scribble becomes a thread.
You already do this in the margins — a triangle for the Trinity, a (C) for the covenants, an anchor for TULIP. Topics gives that instinct a memory: name the idea, define it in your own words, and the app threads it through Scripture, 6,211 letters, and 218 hymns — tagged by hand, or scanned for you by AI against your framing.
- Scan the whole library for a topic you define — every book, every letter, every hymn.
- Trace a doctrine across the centuries — the idea is usually older than its name.

Word vs. definition across history
A doctrine’s idea is often taught long before a single word names it. The Trinity was defined from the earliest letters and Scripture — the term arrived in the 2nd century, and was creedally fixed at Nicaea (325).
Definition (the idea) Word (the term)
Illustrative preview — in the app the scan runs on your own definition.

Why God Allows Evil: Kingdom Theodicy
Gold ticks — where Scripture was quoted.
Speaker referenced Genesis 50:20 · 2:55
Brothers' evil against Joseph; God meant it for good
Speaker quoted Genesis 1:1–2 · 10:07
Earth formless, empty, dark — akin to non-being before Spirit moved
Speaker quoted Matthew 6:10 · 14:53
Lord’s Prayer: kingdom come, will done on earth as in heaven
Then the quiz
Question 2 of 5 According to the speaker’s interpretation of Genesis 1, why does the Bible describe darkness before light?
✓ Correct. “If the light was good, that implies the darkness was evil” — graded against the speaker’s own argument, not a generic answer key.
1. The darkness was created by Satan before God created the light to oppose Him
2. Darkness is simply the absence of light and has no moral significance
3. The darkness represents God’s hiddenness before the incarnation of Christ
4. The darkness represents evil non-being, and the separation of light from darkness implies that darkness was evil

Study Assistant
Ask anything. Get chapter and verse.
Ask the question you’d ask a pastor — “why do people baptize babies?” — and the Study Assistant answers from Scripture and the Reformed confessions. Every verse it cites becomes a tappable chip with the creeds, cross-references, and letters behind it; it points you to Calvin and the church’s own letters; and when it spots a connection worth keeping, it proposes the action — and acts only ever with your yes.
- Positions stay within confessional bounds — Westminster & Scots, cited.
- Proposals, not surprises: Yes, No, or Discuss further on every action.
Your yes required before it touches your library

Why do people baptize babies?
The Covenant Argument is central. In Genesis 17 the covenant sign was applied to infants in the household; Colossians 2:11–12 links baptism to circumcision — so the sign belongs to the children of believing parents too, as whole households were baptized throughout Acts.
An important clarification from the Reformed confessions: baptism is a covenant sign and seal, not a magical rite — its efficacy is not tied to the moment of administration (WCF 28.5–6).
