By What Authority by Mark P. Shea - Catholic Book, Apologetics, 192 pp.
By What Authority, an Evangelical Discovers Catholic Tradition, by Mark P. Shea, is a Catholic apologetic book offered by Our Sunday Visitor, in which the author a former Protestant fundamentalist discovers that evangelical Protestantism is itself based on shaky modern traditions.
As an evangelical, Mark P. Shea accepted the principle of "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 expressed by the Catholic Church, is the only sure gaurantee of the truth of the revelation of Jesus Christ.
"The thing I like most about this book is the crystal clear and compelling case that Shea makes - on the basis of logic, history, and Scripture - for Sacred ("big T") Tradition. It is simply the best that I have found." - Scott Hahn
"This is not just another book of Catholic apologetics. It's not only a good think: it's also a good read. Concrete, clear, compelling arguments." - Peter Kreeft
