Keys Over the Christian World, 2nd ed.

Twenty years in the making, Keys Over the Christian World is a singular study of the papacy, from its beginnings under St. Peter to the year 800 AD. What sets it apart is its foundation: rather than lean on secondary accounts, Scott Butler and John Collorafi draw directly from the original documents, painstakingly translating them into English themselves, many of which have never appeared in English in any form. The sources include the original Latin, Greek, Chaldean, Syriac, Armenian, Coptic, Ethiopian, and others.

From this material the authors weave a picture of the papacy that shows, beyond reasonable doubt, that from its humble beginnings in 33 AD and throughout the first millennium the Church recognized the office as the God-ordained supreme authority over the whole Church, East and West. In its earlier drafts the book had already persuaded a number of dissidents to enter the Catholic Church, so overwhelming is the evidence it gathers.

"John Collorafi and Scott Butler have written an extraordinary work containing a massive and overwhelming presentation of the historical evidence for the truth of Catholic doctrine concerning the primacy of Peter among the apostles and the consequent exercise of universal jurisdiction by the Roman Pontiffs over the Church of both East and West during the First Millennium. Testimonies from the Fathers of the Church, Saints, Popes, the first seven Ecumenical Councils, ancient liturgies, and rare ancient and medieval documents (Latin, Byzantine, Armenian, Syriac, Ethiopian, Coptic) have been painstakingly collected... Some of these valuable testimonies appear in English for the first time in a volume that is unexcelled for its thoroughness. The laborious efforts of the authors have resulted in a resource volume concerning the Papacy that will prove indispensable to Catholic theologians, catechists, and apologists, as well as the ordinary faithful who seek a powerful explanation of the meaning of those awesome Keys handed over to the Prince of the Apostles by the Lord of the Church."
