Sermon research

Search a curated historic Christian library and get every claim with a citation

Theostack answers theological questions from a curated library of historic Christian sources (not the open internet) and attaches each claim to a verifiable work — e.g. Augustine cited by treatise and section. Pastor use: gather named primary-source leads before you open the books yourself.

Read the source: Theostack ↗

Our rule: AI helps with study, research and admin. The pastor still studies, verifies and writes the sermon.

Do the marking yourself, then ask AI only about what you already noticed

A writer documents an analog-first Bible study habit: clean read, marked second pass, color-coded notes and commentaries before ChatGPT ever opens. When she does ask, she treats it as a Socratic partner for Hebrew semantic range and translation comparison on differences she already saw in her own Bibles — not as a ghostwriter. Check every Hebrew or Greek claim in a real lexicon.

Open a chapter's tools, then ask a question with numbered source links

Lumenology puts overview, themes, timeline, commentary, historical commentary, cross-references, and word study beside each chapter, plus a Research Assistant that answers in plain language with numbered citations linked to trusted study sites or (optionally) the open web. Pastor use: gather background and check every numbered source before you teach.

Record your study thoughts and keep them next to your sources

Gemini Notebook's mobile audio recorder captures lectures or your own spoken thoughts and saves them alongside the notebook's sources, so you can chat with them, cite them and keep editing. Pastor use: talk through observations on a passage, or record a class you teach, with the class's consent, then ask cited questions across those notes and your commentaries. Keep pastoral-care conversations out.
