Peter Cardinal Mathews was the former archbishop of the diocese of Cincinnati, Ohio who became the pope of Enigma Babylon One World Faith. Following the Rapture of the current Catholic Pope, Peter Mathews was proclaimed the Pope of the Catholic Church. When the world's religions came together to form a unified doctrine of all religions being valid pathways to God, Mathews became the head, calling himself Peter II, an insult to the papacy as no Pope has ever taken the name of Peter because the the Apostle Peter is recognized as the first Pope of the Catholic Church. Eventually, Pontifex Maximus Peter II's arrogance and his eventual attempt to usurp Nicolae Carpathia's power caused his downfall. He is murdered by the ten subpotentates who use ice daggers from a statue erected for Peter II as predicted in the Book of Revelation.
The Papal name of Peter II may also connect to St. Malachy's Prophecy of the Popes, which states that the last Pope will be named Petrus Romanus (Peter II), "who will reign during the ultimate persecution of the Holy Roman Church".
Afterwards at the Global Gala, Nicolae hypnotizes the crowd to inform them that though they were about to hear of Mathews' death, they would not be shocked at the news; his memorial service was cancelled due to the lack of interest.
