Sources & Scholars

Agape Notes is a study assistant, not an oracle. Every AI-generated sermon draft, consensus view, and topical brief is grounded in a curated whitelist of respected Christian voices — so you always see where an idea comes from, and can verify it yourself.

Modern copyrighted authors are cited and linked — we paraphrase their positions and point you to their publisher, ministry, or books to read them in full.

Public-domain voices (Augustine, Calvin, Luther, Spurgeon, Edwards, Bunyan, Matthew Henry, JFB) may be quoted verbatim with a link to the original source.

A note on citations

AI systems can misattribute quotes. That's why we constrain generation to this whitelist and paraphrase modern authors rather than fabricate direct quotes. Public-domain quotations should still be verified against the original — links are provided wherever possible. If you spot a bad attribution, please let us know.
