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.

Dave Armstrong builds an airtight case from Scripture itself that the Protestant doctrine of *sola Scriptura* fails on its own terms. One hundred numbered arguments organized for easy use, originally edited by Todd Aglialoro and published by Catholic Answers — Catholic apologetics at its most precise.

Fifteen dialogues with educated evangelical Protestants — Presbyterian, Reformed, Baptist, Lutheran — on the three most divisive questions in Christianity: how Scripture and tradition relate, whether the Church can be infallible, and how a person is saved. Drawn from five years of Dave Armstrong's real Internet discussions, lightly tightened for print.

A point-by-point Catholic reply to John Calvin's *Institutes of the Christian Religion* — concentrating on Book IV, *Of the Holy Catholic Church*, where Calvin's contrast with Catholicism is sharpest. 388 pages of Socratic back-and-forth: criticism on the Church, papacy, sacraments, and Eucharist; agreement on 44 more.

Twenty-three of Dave Armstrong's strongest Catholic apologetics essays, drawn from his blog work between 2000 and 2013. Organized under seven headings covering Catholic apologetics method, Bible and Tradition, justification, sacramentalism, purgatory, the communion of saints, and Mary.

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.

Dave Armstrong walks the reader through Catholic salvation theology with 379 Bible passages written out in full — first showing that Catholics embrace grace alone and reject Pelagianism, then devoting the final 115 pages to a chapter-by-chapter biblical refutation of Calvinist TULIP.

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.

Dave Armstrong's biblical case for the doctrines Protestants reject most flatly: an infallible Church and an infallible papacy. 16 chapters, hundreds of verses, with the Catholic argument framed as a sola-Scriptura argument the Protestant is bound by his own rule of faith to consider.

"The historical case for Catholicism becomes stronger as the accumulation of patristic evidence piles up." Dave Armstrong's 284-page patristic case across seven doctrines — Bible and Tradition, justification, the Eucharist, Purgatory, the saints, Mary, and the papacy — with the Protestant scholarly works that corroborate every reading.

Dave Armstrong on the modern Catholic convert wave — its origins, its psychology, and his own journey in. Part I analyzes the conversion process from many angles, Part II tells Dave's own story from clueless curiosity through evangelicalism to Rome, and Part III gathers fifteen older conversion stories now in the public domain.

A rational, side-by-side comparison of the Christian and postmodernist worldviews. Dave Armstrong takes on the problem of evil, the "problem of good" and meaningfulness in atheism, miracles, the relationship of Christianity to science, atheist unproven axioms — and the cosmological and teleological arguments for God's existence.

A "classic Catholic apologetic commentary" — biblical-only excerpts from twelve great Catholic apologists between 1525 and 1925, arranged in biblical order across 228 Scripture passages. From Thomas More and Erasmus to Francis de Sales, Pascal, Newman's contemporary Wiseman, Cardinal Gibbons, and Karl Adam.

Twelve written back-and-forth debates between Dave Armstrong and Reformed Baptist apologist James White, the leading anti-Catholic of his generation. Plus critiques of White's published work. Armstrong's premise: White's debate reputation collapses when arguments are put on paper, footnoted, and answered at length.

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.

A lay-apologetics summary of Catholic teaching on the family and sexuality. Dave Armstrong takes the six issues where the Church's position is hardest to live with — abortion, contraception, extramarital sex, divorce, homosexuality, radical feminism — and shows why Catholics believe what they do, from reason and Scripture rather than rules.

Dave Armstrong's day-by-day journal of his October 2014 pilgrimage to the Holy Land — Caesarea Philippi, the Sea of Galilee, the River Jordan, Bethlehem, the Holy Sepulchre, the Temple Mount — interleaved with five Archaeological Interludes on the current state of the evidence for biblical sites.

A Catholic analysis of Martin Luther in two parts: a critical examination of the founder of Protestantism (his authority claims, his canon, his salvation theology, the Peasants' Revolt, his intolerance), followed by 83 pages of praise — where Luther's Eucharistic theology, Mariology, and sacramental teaching sound surprisingly Catholic.

A second book of essays on three connected topics: the distinction between extreme Catholic reactionaries and mainstream traditionalists, the New Mass and its real liturgical abuses, and genuine — not "silly liberal" — ecumenism. From a Catholic who loves the Tridentine Latin Mass and worships in a reverent Novus Ordo parish.

Dave Armstrong's accessible defense of the Christian faith — written for readers across every branch of Christianity. Modeled in spirit after C. S. Lewis's *Mere Christianity*, it focuses only on the apologetic ground that Catholics, Orthodox, and Protestants hold in common.

The companion volume to *A Biblical Defense of Catholicism* — sixteen chapters of biblical arguments and dialogues for distinctively Catholic doctrines. Less reference, more conversation: most of the book emerged from real internet debates between 1996 and 2000. With a foreword by Dr. Scott Hahn.

A Catholic-Orthodox dialogue in book form. Dave Armstrong's apologetic for Catholicism and respectful critique of Orthodoxy, with significant additional contributions from Byzantine Catholic Fr. Deacon Daniel G. Dozier — feedback, reply, and a closing chapter from the Eastern theological perspective.

A former Protestant campus missionary turns the Bible itself into a case for Catholicism. Sola Scriptura, justification, the Eucharist, Mary, the saints, purgatory, the papacy — each defended from hundreds of verses across 229 of the New Testament’s 259 chapters, plus the Church Fathers and the Catechism.

Fast, substantive answers to over sixty of the most common Protestant challenges — each on a two-page spread with the objection, the Catholic reply, and citations from Scripture, the saints, and respected Protestant scholars. Compact enough to carry, deep enough to settle a debate.

Luther launched the Reformation with 95 anti-Catholic theses; Armstrong answers with 95 pro-Catholic passages from the Bible itself. One of the most accessible Scripture-based introductions to Catholic apologetics in print, by a former Bible-believing Protestant who followed these very passages into the Church.

Eighty short, punchy essays that walk through the central teachings of the Catholic Church and prove each one from Scripture. Endorsed by Tim Staples and Al Kresta. A near-perfect “look it up fast” reference for any apologist.

Editor Dave Armstrong scours Chesterton’s vast and often obscure output to gather his pithiest, most profound, and wittiest one-liners and paragraphs, then organizes them by topic. The Prince of Paradox at his sharpest — a perfect bedside book, gift, or sermon-prep companion.

A topical treasury of John Wesley — founder of Methodism and one of history’s most influential evangelists — arranged alphabetically from “Absolution” to “Zeal.” A standout volume in Armstrong’s Quotable series. Published by a Wesleyan press — a cross-tradition honor to Armstrong’s scholarship.

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.

Subtitled How Archaeology, Science, and History Back Up the Bible, Armstrong marshals secular archaeology, hydrology, zoology, and historical scholarship to show that Scripture’s most “fantastic” episodes are probable, not just possible. Nearly 400 endnotes. Endorsed by Steve Ray and Marcellino D’Ambrosio.
