Get the original essay Pope Leo was known as the killer of heresies, in his time there were so many heresies. There was a difficult time when the Church was faced with the problem of Monophysitism. This heresy was growing stronger and stronger. This heresy proclaimed that the person of Jesus Christ had only one nature rather than two natures, “divine and human”. The heresy that Pope Leo is perhaps most remembered in the Church for suppressing was the heresy of Monophysitism. Pope Leo actively encouraged the convening of the Fourth Ecumenical Council, at Chalcedon in 451 AD, to condemn the heresy of the Monophysites. Nearly 630 bishops were present at the council. Pope Leo taught that Jesus had two natures, divine and human. This teaching was known as “Leon’s Tome.” While Saint-Flavian was faced with the problem of the "Council of Thieves", he wrote this letter. In this letter, Pope Leo mentioned the teaching of the two natures of Jesus. The same letter was read during the council. After reading the letter, most of the bishops exclaimed, “Peter spoke through the mouth of Leo.” However, non-Greek bishops did not agree with this teaching and therefore withdrew from the Church. Pope Leo condemned the actions of the “Council of Thieves” and excommunicated Dioscorus after the Council of Chalcedon. Pope Leo played an important role in saving Rome from the barbarians. In 452 AD, Attila's armies marched on Rome. As soon as Pope Leo heard about Attila's armies, he immediately rushed to meet Attila in northern Italy. After meeting the Pope, Attila was shocked when he saw the Pope's powerful suit. Attila added that I was not afraid as a person who came to meet him, but next to him there was another man dressed in spiritual clothes and in his hand I saw a sword. It was like a miracle; people were shocked hearing this incident. Bishop Julian of Kios, in his letter, speaks of deliverance from the “scourge” as a special gift of divine mercy.
