St. Leo was Roman, At the death of Pope Sixtus, he became Pope.
Those were hard times for the Church because there were barbarian armies attacking Christians in many places and there were many people spreading errors about the Faith. But St. Leo was one of the greatest Popes there ever was. He was absolutely unafraid of anything of anyone. He had great trust in the help of the first Pope, St. Peter the Apostle.
To stop the spread of the false teachings, St. Leo explained the true Faith with his famous writings. He called a council to condemn the wrong doctrines. Those who would not give up their heresy were put out of the Church. Those who were sorry, the Saint received back into the Church and asked people to pray with him for them.
When a great army of barbarians called Huns came to attack the city of Rome, all the people were filled with fear. They knew that the Huns had already burned many cities. To save Rome, St. Leo rode out to meet the terrible enemy leader, Attila. The only weapon he had was his great trust in God! When they met, something wonderful happened. Attila, the cruel pagan leader, showed the Pope great honor, and made a treaty of peace with him. Attila said afterwards that he had seen two mighty figures standing by the Pope while he spoke! These were the great Apostles Peter and Paul, sent by God to protect Pope Leo and the Christians.
Because of his humility and charity, Pope Leo was loved by all. He was Pope for twenty-one years.
We will pray more often for our Holy Father and the Church all over the world.
