One Lord, One Faith: An Introduction to Comparative Christian Doctrine

Author: Vassilios Bakoyannis

Archimandrite Vallilios Bakoyannis serves as an Orthodox priestmonk in Patras, Greece, and has written over thirty books of theological nature in Greek. This work deals with the topic of doctrinal authority in the Church (Scripture and Tradition). It contrasts the teachings of the Orthodox Church with the various approaches of Roman Catholics and Protestants.

Deals with questions such as: How did the Scriptures come about? Is the Church above the Scriptures? Are the Ecumenical Councils, like the Apostolic Council, God-inspired? How does God view a heresy? etc.
