Orthodoxy is the Church of Tradition. Orthodoxy preserves inviolate the dogmas and canons of the Seven Ecumenical Councils. Orthodxy is the Church of the holy and victorious Martyrs, the Church f the holy and God bearing Fathers, the Church which possesses Christianity in its original form; her worship is unadulterated and genuine, and her teaching unchanged. Hence, without a doubt and without a doubt and without any exaggeration whatsoever, only Orthodoxy is the One, Holy, Catholic and Apostolic Church of Christ.
