2 Peter 2.9-22 (Epistle)

9The Lord knoweth how to deliver the godly out of temptations, and to reserve the unjust unto the day of judgment to be punished: 10But chiefly them that walk after the flesh in the lust of uncleanness, and despise government. Presumptuous are they, selfwilled, they are not afraid to speak evil of dignities. 11Whereas angels, which are greater in power and might, bring not railing accusation against them before the Lord. 12But these, as natural brute beasts, made to be taken and destroyed, speak evil of the things that they understand not; and shall utterly perish in their own corruption; 13And shall receive the reward of unrighteousness, as they that count it pleasure to riot in the day time. Spots they are and blemishes, sporting themselves with their own deceivings while they feast with you; 14Having eyes full of adultery, and that cannot cease from sin; beguiling unstable souls: an heart they have exercised with covetous practices; cursed children: 15Which have forsaken the right way, and are gone astray, following the way of Balaam the son of Bosor, who loved the wages of unrighteousness; 16But was rebuked for his iniquity: the dumb ass speaking with man’s voice forbad the madness of the prophet. 17These are wells without water, clouds that are carried with a tempest; to whom the mist of darkness is reserved for ever. 18For when they speak great swelling words of vanity, they allure through the lusts of the flesh, through much wantonness, those that were clean escaped from them who live in error. 19While they promise them liberty, they themselves are the servants of corruption: for of whom a man is overcome, of the same is he brought in bondage. 20For if after they have escaped the pollutions of the world through the knowledge of the Lord and Saviour Jesus Christ, they are again entangled therein, and overcome, the latter end is worse with them than the beginning. 21For it had been better for them not to have known the way of righteousness, than, after they have known it, to turn from the holy commandment delivered unto them. 22But it is happened unto them according to the true proverb, The dog is turned to his own vomit again; and the sow that was washed to her wallowing in the mire.

Mark 13.14-23 (Gospel)

14But when ye shall see the abomination of desolation, spoken of by Daniel the prophet, standing where it ought not, (let him that readeth understand,) then let them that be in Judæa flee to the mountains: 15And let him that is on the housetop not go down into the house, neither enter therein, to take any thing out of his house: 16And let him that is in the field not turn back again for to take up his garment. 17But woe to them that are with child, and to them that give suck in those days! 18And pray ye that your flight be not in the winter. 19For in those days shall be affliction, such as was not from the beginning of the creation which God created unto this time, neither shall be. 20And except that the Lord had shortened those days, no flesh should be saved: but for the elect’s sake, whom he hath chosen, he hath shortened the days. 21And then if any man shall say to you, Lo, here is Christ; or, lo, he is there; believe him not: 22For false Christs and false prophets shall rise, and shall shew signs and wonders, to seduce, if it were possible, even the elect. 23But take ye heed: behold, I have foretold you all things.

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.
