Pope St. Leo reigned twenty-one years as pope in the 5th century, and is the first pope to be titled "the Great." He truly was a great Pope, defending the Faith, and confirming the primacy of the Successors of St. Peter. But perhaps the most exciting thing Pope Leo did was when he had a confrontation with the infamous and cruel military leader, Attila the Hun. This is the story.
The Huns were a nomadic people, originating probably in Mongolia, but they migrated westward, sacking and pillaging whatever cities or towns that were in their way. Until the time of Attila in the 5th century, the Huns were comprised of a loose confederation of tribes, not really a unified people at all – that is, until Attila came on the scene. He unified them, and they were making their sweep across Europe. By the time of Pope Leo, Attila the Hun was busy ransacking most of Italy, and his plan included the sack of Rome. Attila hoped to add it to his possessions, not only for the riches it would give him, but he was also trying add to his number of wives, and the young woman he had his eye on would be impressed with his taking Rome, or so he thought.
Pope Leo, of course, wanted to protect Rome and keep its citizens alive, but here was Attila, looking to attack and plunder the city, and destroy the Church. With the approach of Attila and his mob of soldiers, Pope Leo went into prayer, committing his papacy to the patronage and protection of St. Peter, the apostle and first pope, and then Leo did a very brave thing – he arranged a meeting with Attila just outside the city of Rome. Nobody thought this was a very good idea – in fact, everyone in Rome was sure that Pope Leo would be immediately martyred by this conqueror who never hesitated to murder and destroy anything or anyone who got in his way.
Nonetheless, Pope Leo went to meet Attila. And then, one of the most dramatic moments in Christian history takes place: Attila calls off the sack of Rome. And Leo goes safely back to Rome. What happened? What made Attila retreat?
This is the account of that meeting: while Attila and Leo were conversing, Attila was shaking in his boots, because that during that conversation, Attila saw a vision like he had never seen before! Attila saw St. Peter himself hovering over Leo's head . . . with a huge sword drawn and pointed directly at him! Attila was certain he would be immediately killed if he didn’t withdraw and leave the area, so to save his own skin, Attila ran away from the Pope, who was armed only with the Truth.
And that's the story of how Pope Leo the Great saved Rome from being destroyed.
O Lord Jesu Christ, who didst strengthen thy holy Bishop and Doctor, Pope Leo, to maintain both by word and deed the verity of thy sacred Humanity: grant, we beseech thee; that guided by the light of his doctrine, we may earnestly defend the faith of thy holy Incarnation; who livest and reignest with the Father, in the unity of the Holy Spirit, ever one God, world without end. Amen.
