Reference Essentials (3 Books)

For the studious reader. Three reference-grade volumes — Dave’s flagship Q&A book, Thomistic theology in quote form, and Newman on doctrinal development.

• Revelation! 1001 Bible Answers to Theological Topics — Dave Armstrong asks 1,001 theological questions and lets the Bible answer every one of them. Organized under 18 categories and 200 sub-topics — a quick-reference catechism where Scripture itself is the star, designed for Catholics defending the faith and inquirers wanting to see the biblical case in one place.
• The Quotable Summa Theologica — Dave Armstrong’s topical reference to St. Thomas Aquinas — 214 categories, alphabetically indexed, drawing the theological core of the 3,500-page *Summa Theologica* into a single 200-page volume. The Angelic Doctor, ready to be referenced quickly.
• Development of Catholic Doctrine — Dave Armstrong’s accessible introduction to doctrinal development — the Catholic answer to the Protestant challenge that doctrines unknown to the early Church can’t be apostolic. Eight chapters anchored in John Henry Newman’s classic theory, with the “progressive revelation” in Scripture itself as the starting case.
