ENDORSEMENTS

“Dave Armstrong is a master of biblical citation and compressing arguments. He does in a few pages what many apologists take chapters to accomplish.”

Al Kresta, Host of Kresta in the Afternoon

***

“A treasure-trove of biblical texts demonstrating the veracity of the Catholic Faith. This is a must-read for Catholics and non-Catholics alike.”

Tim Staples, Catholic apologist (at Catholic Answers) and Author

***

“Sophia Press is offering a collection of eighty short essays by Catholic convert and apologist Dave Armstrong, entitled Proving the Catholic Faith is Biblical. Reading this is very like reading a collection of CatholicCulture.org’s commentaries by Phil Lawler or myself; the little essays are drawn chiefly from Armstrong’s excellent work online addressing questions that come up again and again as Protestants challenge the faith of their Catholic neighbors. A great many individual topics are covered, but the subtitle will give you the idea: ‘From priestly celibacy to the Rosary’.

Dr. Jeff Mirus, review of four Sophia books, at CatholicCulture.Org (8-18-15)

INTRODUCTION

***

This is a collection of essays that are (1) short (usually two or three pages), (2) characterized by lots of biblical argumentation, and (3) written in defense of Catholicism (apologetics). Most of them came about as a result of my ongoing efforts to comment on issues that regularly come up in “worlds” of Catholic apologetics and theology online.

The brevity of the chapters indicates the trend in my apologetic writing for many years now: “quick,” precise answers to apologetics questions. For better or ill, this is the world that we live in, and the apologist must make efforts (as St. Paul did, and as Vatican II stressed) to meet people where they are.

I don’t deny the continuing utility and necessity of longer treatments (my “corpus” still contains plenty of those!), but most people prefer shorter essays, and their interest in theology and apologetics generally doesn’t extend to treatise-length expositions. This is all the truer for beginners in theology.

Many of these essays were written as columns for Seton Magazine, which is devoted to Catholic homeschoolers. Others came from my regular column in The Michigan Catholic, the official newspaper for the Archdiocese of Detroit. Some were originally posted as part of my work in the Internet forum of the Coming Home Network from 2007-2010 (I was the head moderator during that period), and several were initiated on Facebook. All of these essays are meant to answer the questions that people ask and to make the Catholic Faith more understandable, leading to a confident belief and the ability to “make a defense” (1 Pet. 3:15) for this Faith as opportunities arise. I hope by God’s grace I have accomplished these goals.

Thanks so much for reading, and God bless you!
