Guerricus of Petra

When it was decided to restore the ancient diocese of Petra, the choice of bishop fell to Amalric of Nesle, Patriarch of Jerusalem, who appointed Guerricus.

[4] According to the 13th-century jurist John of Ibelin, that prior to 1167 there was an archbishop at Babbat que les Grecs apelent Filadelfe (Rabba, which the Greeks call Philadelphia), either Bozrah or Amman, which was transferred in that year to Crac, et est appelé l'arcêveque de la Pierre dou Desert (Kerak, which is called the archbishopric of Petra of the Desert).

[5] The archbishops of Petra had been the metropolitans of the old Roman province of Arabia Petraea, which had been subject to the patriarch of Antioch in antiquity.

[2][7] In some late documents he is called archiepiscopus de Monte Regali, archbishop of Montréal, which was, along with Kerak, one of the major castles of Oultrejordain.

[8] There are references to a Greek Orthodox bishop at Mount Sinai (which the Crusaders called Faraon) under the jurisdiction of Petra during Guerricus's time, but it is doubtful that the archbishop of Petra could have exercised any real authority over the Greek Orthodox church in Sinai, where Crusader control was fleeting.
