Syrian born Pope John V only ruled for a year but his contributions to the faith before becoming Pope were immeasurable. In 680 John was the leading Roman delegate at the Third Council of Constantinople. This council was called to finally put to rest the leading heresy of the day,monothelitism. This heresy believed that Jesus had only a Divine will,and not both human and Divine as the Church teaches. It was popular with various emperors and even some clergy of the eastern Church,but Rome had always held the line on the nature of Jesus for nearly two hundred years at this point(and seemingly forever when writing this blog).John and the other Roman delegate’s defense of the nature of Jesus finally helped put to rest this long standing debate and monothelitism was officially declared a heresy recognized by both west and east Churches. This work on behalf of the Catholic faith helped to elect him to the Papacy in 685. John mostly used his short time clearing up debates about the appointing of bishops and restoring older Churches. He was buried in St Peter’s basilica(the old one)and unfortunately his tomb was destroyed by an Arab invasion of Rome in 846.
