1 Peter 1.1-2, 10-12, 2.6-10 (Epistle)

1Peter, an apostle of Jesus Christ, to the chosen ones who are living as foreigners in the Dispersion in Pontus, Galatia, Cappadocia, Asia, and Bithynia, 2according to the foreknowledge of God the Father, in sanctification of the Spirit, that you may obey Jesus Christ and be sprinkled with his blood: Grace to you and peace be multiplied.

10Concerning this salvation, the prophets sought and searched diligently. They prophesied of the grace that would come to you, 11searching for who or what kind of time the Spirit of Christ which was in them pointed to when he predicted the sufferings of Christ and the glories that would follow them. 12To them it was revealed that they served not themselves, but you, in these things, which now have been announced to you through those who preached the Good News to you by the Holy Spirit sent out from heaven; which things angels desire to look into. 6Because it is contained in Scripture, “Behold, I lay in Zion a chief cornerstone, chosen and precious. He who believes in him will not be disappointed.”

7For you who believe therefore is the honor, but for those who are disobedient, “The stone which the builders rejected has become the chief cornerstone,”

8and, “a stumbling stone and a rock of offense.” For they stumble at the word, being disobedient, to which also they were appointed. 9But you are a chosen race, a royal priesthood, a holy nation, a people for God’s own possession, that you may proclaim the excellence of him who called you out of darkness into his marvelous light. 10In the past, you were not a people, but now are God’s people, who had not obtained mercy, but now have obtained mercy.

Mark 12.1-12 (Gospel)

1He began to speak to them in parables. “A man planted a vineyard, put a hedge around it, dug a pit for the wine press, built a tower, rented it out to a farmer, and went into another country. 2When it was time, he sent a servant to the farmer to get from the farmer his share of the fruit of the vineyard. 3They took him, beat him, and sent him away empty. 4Again, he sent another servant to them; and they threw stones at him, wounded him in the head, and sent him away shamefully treated. 5Again he sent another, and they killed him, and many others, beating some, and killing some. 6Therefore still having one, his beloved son, he sent him last to them, saying, ‘They will respect my son.’ 7But those farmers said among themselves, ‘This is the heir. Come, let’s kill him, and the inheritance will be ours.’ 8They took him, killed him, and cast him out of the vineyard. 9What therefore will the lord of the vineyard do? He will come and destroy the farmers, and will give the vineyard to others. 10Haven’t you even read this Scripture: ‘The stone which the builders rejected was made the head of the corner. 11This was from the Lord. It is marvelous in our eyes’?”

12They tried to seize him, but they feared the multitude; for they perceived that he spoke the parable against them. They left him and went away.

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.
