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

1Peter, an apostle of Jesus Christ, to the strangers scattered throughout Pontus, Galatia, Cappadocia, Asia, and Bithynia, 2Elect according to the foreknowledge of God the Father, through sanctification of the Spirit, unto obedience and sprinkling of the blood of Jesus Christ: Grace unto you, and peace, be multiplied. 10Of which salvation the prophets have enquired and searched diligently, who prophesied of the grace that should come unto you: 11Searching what, or what manner of time the Spirit of Christ which was in them did signify, when it testified beforehand the sufferings of Christ, and the glory that should follow. 12Unto whom it was revealed, that not unto themselves, but unto us they did minister the things, which are now reported unto you by them that have preached the gospel unto you with the Holy Ghost sent down from heaven; which things the angels desire to look into. 6Wherefore also it is contained in the scripture, Behold, I lay in Sion a chief corner stone, elect, precious: and he that believeth on him shall not be confounded. 7Unto you therefore which believe he is precious: but unto them which be disobedient, the stone which the builders disallowed, the same is made the head of the corner, 8And a stone of stumbling, and a rock of offence, even to them which stumble at the word, being disobedient: whereunto also they were appointed. 9But ye are a chosen generation, a royal priesthood, an holy nation, a peculiar people; that ye should shew forth the praises of him who hath called you out of darkness into his marvellous light: 10Which in time past were not a people, but are now the people of God: which had not obtained mercy, but now have obtained mercy.

Mark 12.1-12 (Gospel)

1And he began to speak unto them by parables. A certain man planted a vineyard, and set an hedge about it, and digged a place for the winefat, and built a tower, and let it out to husbandmen, and went into a far country. 2And at the season he sent to the husbandmen a servant, that he might receive from the husbandmen of the fruit of the vineyard. 3And they caught him, and beat him, and sent him away empty. 4And again he sent unto them another servant; and at him they cast stones, and wounded him in the head, and sent him away shamefully handled. 5And again he sent another; and him they killed, and many others; beating some, and killing some. 6Having yet therefore one son, his wellbeloved, he sent him also last unto them, saying, They will reverence my son. 7But those husbandmen said among themselves, This is the heir; come, let us kill him, and the inheritance shall be ours. 8And they took him, and killed him, and cast him out of the vineyard. 9What shall therefore the lord of the vineyard do? he will come and destroy the husbandmen, and will give the vineyard unto others. 10And have ye not read this scripture; The stone which the builders rejected is become the head of the corner: 11This was the Lord’s doing, and it is marvellous in our eyes? 12And they sought to lay hold on him, but feared the people: for they knew that he had spoken the parable against them: and they left him, and went their way.

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.
