The Correspondence between the Tubingen Theologians and Patriarch Jeremias II of Constantinople on the Augsburg Confession.

Augsburg and Constantinople was the crowning achievement of the late Very Reverend Father George Mastrantonis, a distinguished Orthodox clergyman and prolific author. First published in 1982, this book remains a work of vital interest to scholars of all faiths. The correspondence between the Lutheran theologians of Tubingen and Orthodox Patriarch Jeremiah II may be seen as the first substantive ecumenical dialogue of the post Reformation era. More than four hundred years later, these exchanges continue to have value well beyond the purely historical. In preparing this translation and commentary, Father Mastrantonis believed that these documents are "especially important today when a movement toward better understanding among churches is taking place."
