2 Peter 1.1-10 (Epistle)

1Simon Peter, a servant and an apostle of Jesus Christ, to them that have obtained like precious faith with us through the righteousness of God and our Saviour Jesus Christ: 2Grace and peace be multiplied unto you through the knowledge of God, and of Jesus our Lord, 3According as his divine power hath given unto us all things that pertain unto life and godliness, through the knowledge of him that hath called us to glory and virtue: 4Whereby are given unto us exceeding great and precious promises: that by these ye might be partakers of the divine nature, having escaped the corruption that is in the world through lust. 5And beside this, giving all diligence, add to your faith virtue; and to virtue knowledge; 6And to knowledge temperance; and to temperance patience; and to patience godliness; 7And to godliness brotherly kindness; and to brotherly kindness charity. 8For if these things be in you, and abound, they make you that ye shall neither be barren nor unfruitful in the knowledge of our Lord Jesus Christ. 9But he that lacketh these things is blind, and cannot see afar off, and hath forgotten that he was purged from his old sins. 10Wherefore the rather, brethren, give diligence to make your calling and election sure: for if ye do these things, ye shall never fall:

Mark 13.1-8 (Gospel)

1And as he went out of the temple, one of his disciples saith unto him, Master, see what manner of stones and what buildings are here! 2And Jesus answering said unto him, Seest thou these great buildings? there shall not be left one stone upon another, that shall not be thrown down. 3And as he sat upon the mount of Olives over against the temple, Peter and James and John and Andrew asked him privately, 4Tell us, when shall these things be? and what shall be the sign when all these things shall be fulfilled? 5And Jesus answering them began to say, Take heed lest any man deceive you: 6For many shall come in my name, saying, I am Christ; and shall deceive many. 7And when ye shall hear of wars and rumours of wars, be ye not troubled: for such things must needs be; but the end shall not be yet. 8For nation shall rise against nation, and kingdom against kingdom: and there shall be earthquakes in divers places, and there shall be famines and troubles: these are the beginnings of sorrows.

St Leo the Great, pope of Rome(461)

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.
