St. Sophronius of Jerusalem
Apostolic See, Foundation of the Church, St. Peter
“Teaching us all orthodoxy and destroying all heresy and driving it away from the God-protected halls of our holy Catholic Church. And together with these inspired syllables and characters, I accept all his (the pope’s) letters and teachings as proceeding from the mouth of Peter the Coryphaeus, and I kiss them and salute them and embrace them with all my soul … I recognize the latter as definitions of Peter and the former as those of Mark, and besides, all the heaven-taught teachings of all the chosen mystagogues of our Catholic Church.” (Saint Sophronius, Patriarch of Jerusalem, Mansi, xi. 461 [c. A.D. 638]).
“Transverse quickly all the world from one end to the other until you come to the Apostolic See (Rome), where are the foundations of the orthodox doctrine. Make clearly known to the most holy personages of that throne the questions agitated among us. Cease not to pray and to beg them until their apostolic and Divine wisdom shall have pronounced the victorious judgement and destroyed from the foundation …the new heresy.” (Sophronius, [quoted by Bishop Stephen of Dora to Pope Martin I at the Lateran Council], Mansi, 893).
