The purpose of thesynod was to counter what Eastern Orthodox considered asRoman Catholic andProtestant doctrinal errors that had enteredEastern Orthodox Christian theology, and to offer a comprehensive Eastern Orthodox statement on the content and character of the Eastern Orthodox faith.[4]
Including representatives of the Greek and Slavic Churches, it condemned theCalvinist teachings ascribed toCyril Lucaris and ratified (a somewhat amended text of)Peter Mogila'sExpositio fidei (Statement of Faith, also known as theOrthodox Confession), a description of Christianorthodoxy in a question and answer format.[5][6][7] TheStatement of Faith became fundamental for establishing the Eastern Orthodox world's attitude towardReformation thought. The major contribution of the synod was the reinforced sense of unity in theEastern Orthodox Church through the promulgation of an authoritative statement agreed upon by all the major sees.[4]
