Unlike most emperors before him, who were Monophysite, Justin was a devout Orthodox Christian. Monophysites and the Orthodox were in conflict over the dual natures of Christ. Past emperors had supported the Monophysites' position, which was in direct conflict with the Orthodox teachings of the Papacy, and this strife led to the Acacian Schism. Justin, as an Orthodox, and the new patriarch, John of Cappadocia, immediately set about repairing relations with Rome. After delicate negotiations, the Acacian Schism ended in late March, 519.
