5. Of ANTIOCH (2). Contemporary with Michael Cerularius, patriarch of Constantinople [MICHAEL, No. 6], and Leo of Achridia [LEO, No. 2], and united with them in hostility to the Latin Church, was Petrus or Peter, the third patriarch of Antioch of that name in the current tables of the occupants of that see, which commence with the Apostle Peter. Peter obtained the patriarchate in the year 1053, and in the same year he sent synodical letters to the patriarchs of Alexandria, Jerusalem, and Constantinople, and to the pope, Leo IX., signifying his accession.
Profession of Faith
Cave states that he sent to the pope "a profession of his faith," but it is probable that he has applied this term to the synodical letter, of which a Latin version appears among the letters of Leo IX.; but Le Quien, who had in his possession the Greek text of these synodical letters, complains of the great discrepancy between the Greek text and the Latin version.
Two letters of Peter appear in Greek with a Latin version, in the Monumenta Ecclesiae Graecae,
of Cotelerius, vol. ii. pp. 112, 145.
The first is entitled Epistola ad Dominicum Gradensem,
and is an answer to Dominicus Gradensis s. Venetus, patriarch of Venice or Aquileia, whose letter, in the collection of Cotelerius, precedes that of Peter; the second is addressed to Michael Cerularius, Epistola ad Michaelem Cerulariwm,
and is preceded by a letter of Michael to Peter, to which it is the answer.
A considerable part of this letter had previously been published by Leo Allatius, in his De Consensu Ecclesiarum Orient. et Occident.
According to Cave, Peter bitterly inveighed against the lives and doctrines of the Latin clergy, and especially against the addition of the words "filioque" to the creed; while, according to Le Quien, he preserved a more impartial tone, and showed every where "a disposition averse to schism."
There is extant in MS. at Vienna, another letter of Peter, Petri Epistola ad Joannem Tranensem in Apulia Episcopum,
relating to the matters in dispute between the Eastern and Western Churches.
