By What Authority?: An Evangelical Discovers Catholic Tradition

In this newly updated, expanded version of his popular work of apologetics, Mark P. 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.
