The Bible Tells Me So cover

The Bible Tells Me So

Reverses the usual debate: instead of defending Catholic doctrines against Protestant proof-texts, Armstrong puts the burden of proof back on the Bible itself. Short chapters pose biblical challenges that don’t fit a sola Scriptura framework. Sharp, brief, and ideal for handing to a Protestant friend.

Biblical Catholic Eucharistic Theology cover

Biblical Catholic Eucharistic Theology

Twenty-three Scripture-packed chapters on the Real Presence and the Sacrifice of the Mass, drawn from fifteen years of Dave Armstrong's online dialogues. The deeper course on Catholic eucharistic doctrine, presupposing the basics: doubting disciples in John 6, St. Augustine, John Calvin, the Protestant "idolatry" charge, and the Church Fathers.

Biblical Evidence for the Communion of Saints cover

Biblical Evidence for the Communion of Saints

Twenty-one chapters of Scripture-based defense of the Catholic communion of saints — invocation, intercession, veneration, images, relics, purgatory, prayer for the dead, and penance — drawn from sixteen years of Dave Armstrong's online dialogues with Protestants. The biblical case for the doctrines Protestants most often call un-biblical.

Cardinal Newman: Q  A in Theology, Church History, and Conversion cover

Cardinal Newman: Q & A in Theology, Church History, and Conversion

Blessed John Henry Cardinal Newman insisted, in letter after letter, “I am not a theologian.” This Q&A–format companion answers what he was right about — and where his deep, original Catholic mind shaped the questions that still matter. Drawn from Newman’s correspondence and essays on theology, Church history, and conversion.

"The Catholic Mary": Quite Contrary to the Bible? cover

"The Catholic Mary": Quite Contrary to the Bible?

Dave Armstrong's case that the "Catholic" Mary and the "biblical" Mary are one and the same. Twenty-one chapters defending every Marian doctrine Protestants single out — the Immaculate Conception, the Assumption, perpetual virginity, the Rosary, Mary as Mediatrix, and the "flowery" devotional traditions like Louis de Montfort and Liguori.

Development of Catholic Doctrine: Evolution, Revolution, or an Organic Process? cover

Development of Catholic Doctrine: Evolution, Revolution, or an Organic Process?

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.

Pillars of Sola Scriptura cover

Pillars of Sola Scriptura

A book-length response to the two most respected classical defenders of sola Scriptura — the 16th-century Calvinist Anglican William Whitaker, whose Disputation on Holy Scripture James White still calls essential reading, and the 19th-century Anglican William Goode, whose Divine Rule of Faith and Practice modern Presbyterian David T. King calls “never been surpassed.”

Pope Francis Explained: Survey of Myths, Legends, and Catholic Defenses in Harmony with Tradition cover

Pope Francis Explained: Survey of Myths, Legends, and Catholic Defenses in Harmony with Tradition

Everyone wants to make the pope into their own image. The secular and dissenting left needs a “progressive” Francis who will finally bring the Church into the modern world. Radical Catholic reactionaries need a “liberal” Francis to alarm them into nostalgia. Mainstream traditionalists, devout and orthodox, find themselves quietly confused.

Protestantism: Critical Reflections of an Ecumenical Catholic cover

Protestantism: Critical Reflections of an Ecumenical Catholic

A Pensées-style critique of Protestantism — 272 numbered “sayings” across ten chapters, modeled in form after Blaise Pascal. The aim is not to attack individual Protestants but to examine the formal principles of Protestantism — sola Scriptura, the invisible church, private judgment, the perspicuity of Scripture, predestination, Luther and Protestant origins — and some of the system’s negative tendencies in practice.

The Quotable Augustine: Distinctively Catholic Elements in His Theology cover

The Quotable Augustine: Distinctively Catholic Elements in His Theology

Reformed Protestants have long claimed St. Augustine as their own. The “allegiance” of these two men — Luther and Calvin — to Augustine, closely examined, is selective and a “mixed record” at best. Dave Armstrong systematically documents what Augustine actually taught on the doctrines historic Protestantism has rejected: baptismal regeneration, the Sacrifice of the Mass, the intercession of the saints, the perpetual virginity of Mary, the primacy of Peter, infused justification, the falsity of sola fide.

The Quotable Eastern Church Fathers: Distinctively Catholic Elements in Their Theology cover

The Quotable Eastern Church Fathers: Distinctively Catholic Elements in Their Theology

The Eastern Fathers are not foreign territory to Catholic doctrine. This collection is devoted to documentation of examples of “distinctively Catholic” theological beliefs or doctrines in the Eastern Church fathers — teachings in harmony with historic Catholic faith but at odds with one or more strains of Protestantism, liberal theology, or modern Eastern Orthodox polemics.

The Quotable Summa Theologica cover

The Quotable Summa Theologica

St. Thomas Aquinas (1225–1274) was without question the greatest theologian in the history of the Catholic Church, and the Summa Theologica (1271–1274) his masterpiece — one of the most influential theological books ever written. The goal here is to make the thought and reasoning of that compendium of the Angelic Doctor more accessible and able to be referenced quickly.

Reflections on Radical Catholic Reactionaries cover

Reflections on Radical Catholic Reactionaries

Dave Armstrong’s first book on radical Catholic reactionaries — 339 numbered “sayings” arranged across sixteen chapters, modeled in form after Blaise Pascal’s Pensées. The aim is not a legalistic canon-law dispute but a presupposition-level critique: the premises, the spirit, and the “quasi-schismatic mentality” of a sociological sub-group that judges its own bishops, popes, and councils.

Revelation! 1001 Bible Answers to Theological Topics cover

Revelation! 1001 Bible Answers to Theological Topics

The Bible is a complex collection of 73 books. Dave Armstrong’s aim — simple in concept, far harder in execution — is to make it easy to find the biblical answer to a theological question, fast. Across 1,001 questions organized under 18 broad categories and 200 sub-topics, the format is built on a quiet inversion: Armstrong supplies the question, and Scripture itself supplies the answer.

Victorian King James Version of the New Testament cover

Victorian King James Version of the New Testament

A New Testament that retains the grandeur and majesty of the 1611 Authorized Version’s English — without the archaisms. This is the selling point: updating the KJV with a 19th century high Victorian style that would have some strong sense of stylistic similarity to Elizabethan English. Not a new translation, but a verse-by-verse selection from six public-domain texts already revered by scholars.
