2 Peter 1.1-10 (Epistle)

1Simon Peter, a servant and apostle of Jesus Christ, to those who have obtained a like precious faith with us in the righteousness of our God and Savior, Jesus Christ: 2Grace to you and peace be multiplied in the knowledge of God and of Jesus our Lord, 3seeing that his divine power has granted to us all things that pertain to life and godliness, through the knowledge of him who called us by his own glory and virtue, 4by which he has granted to us his precious and exceedingly great promises; that through these you may become partakers of the divine nature, having escaped from the corruption that is in the world by lust. 5Yes, and for this very cause adding on your part all diligence, in your faith supply moral excellence; and in moral excellence, knowledge; 6and in knowledge, self-control; and in self-control, perseverance; and in perseverance, godliness; 7and in godliness, brotherly affection; and in brotherly affection, love. 8For if these things are yours and abound, they make you to not be idle or unfruitful in the knowledge of our Lord Jesus Christ. 9For he who lacks these things is blind, seeing only what is near, having forgotten the cleansing from his old sins. 10Therefore, brothers, be more diligent to make your calling and election sure. For if you do these things, you will never stumble.

Mark 13.1-8 (Gospel)

1As he went out of the temple, one of his disciples said to him, “Teacher, see what kind of stones and what kind of buildings!”

2Jesus said to him, “Do you see these great buildings? There will not be left here one stone on another, which will not be thrown down.”

3As he sat on the Mount of Olives opposite the temple, Peter, James, John, and Andrew asked him privately, 4“Tell us, when will these things be? What is the sign that these things are all about to be fulfilled?”

5Jesus, answering, began to tell them, “Be careful that no one leads you astray. 6For many will come in my name, saying, ‘I am he!’ and will lead many astray.

7“When you hear of wars and rumors of wars, don’t be troubled. For those must happen, but the end is not yet. 8For nation will rise against nation, and kingdom against kingdom. There will be earthquakes in various places. There will be famines and troubles. These things are the beginning of birth pains.

St Leo the Great, Pope of Rome

Pope Leo was one of the great bastions of Orthodoxy during the time of the monophysite heresy and its offshoots. ‘According to some, this Saint was born in Rome, but according to others in Tyrrenia (Tuscany), and was consecrated to the archiepiscopal throne of Rome in 440. In 448, when St Flavian, Archbishop of Constantinople [also commemorated today], summoned Eutyches, an archimandrite in Constantinople, to give account for his teaching that there was only one nature in Christ after the Incarnation, Eutyches appealed to St Leo in Rome. After St Leo had carefully examined Eutyches’ teachings, he wrote an epistle to St Flavian, setting forth the Orthodox teaching of the person of Christ, and His two natures, and also counseling Flavian that, should Eutyches sincerely repent of his error, he should be received back with all good will. At the Council held in Ephesus in 449, which was presided over by Dioscorus, Patriarch of Alexandria (and which Saint Leo, in a letter to the holy Empress Pulcheria in 451, was the first to call “The Robber Council”), Dioscorus, having military might behind him, did not allow Saint Leo’s epistle to Flavian to be read, although repeatedly asked to do so; even before the Robber Council was held, Dioscorus had uncanonically received the unrepentant Eutyches back into communion. Because Saint Leo had many cares in Rome owing to the wars of Attila the Hun and other barbarians, in 451 he sent four delegates to the Fourth Ecumenical Council, where 630 Fathers gathered in Chalcedon during the reign of Marcian, to condemn the teachings of Eutyches and those who supported him. Saint Leo’s epistle to Flavian was read at the Fourth Council, and was confirmed by the Holy Fathers as the Orthodox teaching on the incarnate Person of our Lord; it is also called the “Tome of Leo.” The Saint wrote many works in Latin; he reposed in 461.’(Great Horologion).

St Leo is remembered for saving Rome from conquest by Attila the Hun. When Attila drew near to Rome, preparing to pillage the city, St Leo went out to him in his episcopal vestments and enjoined him to turn back. For reasons unknown to worldly historians, the pitiless Attila with all his troops abandoned their attack and returned the way they had come.
