Hebrews 5.11-6.8 (Epistle)

11Of whom we have many things to say, and hard to be uttered, seeing ye are dull of hearing. 12For when for the time ye ought to be teachers, ye have need that one teach you again which be the first principles of the oracles of God; and are become such as have need of milk, and not of strong meat. 13For every one that useth milk is unskilful in the word of righteousness: for he is a babe. 14But strong meat belongeth to them that are of full age, even those who by reason of use have their senses exercised to discern both good and evil.

1Therefore leaving the principles of the doctrine of Christ, let us go on unto perfection; not laying again the foundation of repentance from dead works, and of faith toward God, 2Of the doctrine of baptisms, and of laying on of hands, and of resurrection of the dead, and of eternal judgment. 3And this will we do, if God permit. 4For it is impossible for those who were once enlightened, and have tasted of the heavenly gift, and were made partakers of the Holy Ghost, 5And have tasted the good word of God, and the powers of the world to come, 6If they shall fall away, to renew them again unto repentance; seeing they crucify to themselves the Son of God afresh, and put him to an open shame. 7For the earth which drinketh in the rain that cometh oft upon it, and bringeth forth herbs meet for them by whom it is dressed, receiveth blessing from God: 8But that which beareth thorns and briers is rejected, and is nigh unto cursing; whose end is to be burned.

Mark 8.30-34 (Gospel)

30And he charged them that they should tell no man of him. 31And he began to teach them, that the Son of man must suffer many things, and be rejected of the elders, and of the chief priests, and scribes, and be killed, and after three days rise again. 32And he spake that saying openly. And Peter took him, and began to rebuke him. 33But when he had turned about and looked on his disciples, he rebuked Peter, saying, Get thee behind me, Satan: for thou savourest not the things that be of God, but the things that be of men.

34And when he had called the people unto him with his disciples also, he said unto them, Whosoever will come after me, let him deny himself, and take up his cross, and follow me.

Holy Martyrs Thyrsus, Leucis and Callinicus (250)

These martyrs contested in Asia Minor during the reign of Decius. Thyrsus and Leucis were executed after horrible torture for confessing themselves as Christians and rebuking the Governor for his slaughter of their brethren. Callinicus was a pagan priest, converted by witnessing the martyrdom and miracles of St Thyrsus; he was beheaded.

Holy Martyrs Philemon, Apollonius, Arian and those with them (3rd c.)

“During the reign of Diocletian (284-305), the Governor of Antinoe in the Thebaid of Upper Egypt was Arian, a fierce persecutor who had sent many Christians to a violent death, among them Saints Timothy and Maura (see May 3) and Saint Sabine (Mar. 16). When he had imprisoned thirty-seven Christians for their confession of faith, one of them, named Apollonius, a reader of the Church, lost his courage at the sight of the instruments of torture, and thought how he might escape torments without denying Christ. He gave money to Philemon, a flute-player and a pagan, that he might put on Apollonius’ clothes and offer sacrifices before Arian, so that all would think Apollonius to have done the Governor’s will, and he might be released. Philemon agreed to this, but when the time came to offer sacrifice, enlightened by divine grace, he declared himself a Christian instead. He and Apollonius, who also confessed Christ when the fraud was exposed, were both beheaded. Before beheading them, Arian had commanded that they be shot with arrows, but while they remained unharmed, Arian himself was wounded by one of the arrows; Saint Philemon foretold that after his martyrdom, Arian would be healed at his tomb. When this came to pass, Arian, the persecutor who had slain so many servants of Christ, himself believed in Christ and was baptized with four of his body-guards. Diocletian heard of this and had Arian and his body-guards brought to him. For their confession of Christ, they were cast into the sea, and received the crown of life everlasting.” (Great Horologion)
