Product Description

  • By What Authority: An Evangelical Discovers Catholic Tradition
  • From an award-winning columnist
  • Newly updated and expanded
  • Intellectually and spiritually awakening


In this newly updated, expanded version of his popular work of apologetics, Shea presents a lively and entertaining look at his conversion to Catholicism from Evangelicalism and his discovery of Christian tradition.

As an Evangelical, Shea accepted the principle of "sola scriptura" (Scripture alone) as the basis of faith. Now as a Catholic convert, he skillfully explains how and why Sacred Tradition occupies a central role in Divine Revelation.

Tracing his own journey of intellectual and spiritual awakening, Shea begins by looking for a rejoinder to those modern-day false prophets who would claim that Scripture itself is not to be trusted, and ends with his conviction that tradition, as explained by the Catholic Church, is the only sure guarantee of the truth of the revelation of Jesus Christ.


Mark Shea is an award-winning columnist for the National Catholic Register, and a frequent contributor to Our Sunday Visitor and other Catholic publications. He is a popular blogger, and frequent guest on radio and television.


"A crystal clear and compelling case for Sacred Tradition, on the basis of logic, history and Scripture. It is simply the best I have found."
- Scott Hahn, Author, Rome Sweet Home

"This is not just another book of Catholic apologetics. It is not only a good think; it's also a good read. Concrete, clear, compelling arguments." 
- Peter Kreeft, Author, Handbook of Catholic Apologetics

"An important service for Catholics, Evangelicals and all those seeking a firm grounding for Faith. Shea argues powerfully for the extra-biblical authority of Sacred Tradition as a depository and source of revelation side by side with the Bible, to which it testifies and which it interprets with authority." 
- Russell Shaw, Author, American Church

By What Authority

Review: An excellent presentatio of why Tradition coupled with Scripture must be part of Christian heritage. Citing references that extend back to the earliest days of the young church, this is a satisfying read. Mark Shea traces his journey into the fullness of faith with humor and candor. He should be admired for brevity, while stressing the essentials. For one who questions the authentic development of Christian tradition, or as a reply to someone who disparages it,this book is the ultimate resource.
