Romans 11.13-24 (Epistle)

13For I speak to you Gentiles, inasmuch as I am the apostle of the Gentiles, I magnify mine office: 14If by any means I may provoke to emulation them which are my flesh, and might save some of them. 15For if the casting away of them be the reconciling of the world, what shall the receiving of them be, but life from the dead? 16For if the firstfruit be holy, the lump is also holy: and if the root be holy, so are the branches. 17And if some of the branches be broken off, and thou, being a wild olive tree, wert graffed in among them, and with them partakest of the root and fatness of the olive tree; 18Boast not against the branches. But if thou boast, thou bearest not the root, but the root thee. 19Thou wilt say then, The branches were broken off, that I might be graffed in. 20Well; because of unbelief they were broken off, and thou standest by faith. Be not highminded, but fear: 21For if God spared not the natural branches, take heed lest he also spare not thee. 22Behold therefore the goodness and severity of God: on them which fell, severity; but toward thee, goodness, if thou continue in his goodness: otherwise thou also shalt be cut off. 23And they also, if they abide not still in unbelief, shall be graffed in: for God is able to graff them in again. 24For if thou wert cut out of the olive tree which is wild by nature, and wert graffed contrary to nature into a good olive tree: how much more shall these, which be the natural branches, be graffed into their own olive tree?

Matthew 11.27-30 (Gospel)

27All things are delivered unto me of my Father: and no man knoweth the Son, but the Father; neither knoweth any man the Father, save the Son, and he to whomsoever the Son will reveal him.

28Come unto me, all ye that labour and are heavy laden, and I will give you rest. 29Take my yoke upon you, and learn of me; for I am meek and lowly in heart: and ye shall find rest unto your souls. 30For my yoke is easy, and my burden is light.

Hieromartyr Athenogenes, bishop of Sebaste, and his ten disciples (311)

“In the time of Diocletian, a fierce persecutor of Christians called Philomarchus came to Sebaste. He arrested and killed many Christians in the town. When he saw Athenogenes and his disciples, he told the elder to sacrifice to the idols, that they should not perish as had the other Christians. Athenogenes replied: ‘O Torturer, those whom you describe as having perished have not perished, but are in heaven and make merry with the angels!’ There was a touching moment when a deer, which had been hand-fed by the compassionate Athenogenes, ran up to him and, seeing him in such straits, shed tears. Wild animals of the hills had more pity on the martyrs than did the pagans! After harsh torture, during which an angel of God comforted them, they were all beheaded, first the priests and fellow workers of Athenogenes and then Athenogenes himself, and went to their heavenly home in the year 311.” (Prologue)

The Great Horologion adds “There is a second Martyr Athenogenes commemorated today, mentioned by St Basil… it is said that as this Athenogenes approached the fire, wherein he was to die a martyric death, he chanted the hymn O Joyous Light in praise of the Holy Trinity.” This is one way that we know that the vesperal hymn Gladsome Light was in use before the time of St Basil the Great.
