Romans 15.7-16 (Epistle)

7Wherefore receive ye one another, as Christ also received us to the glory of God. 8Now I say that Jesus Christ was a minister of the circumcision for the truth of God, to confirm the promises made unto the fathers: 9And that the Gentiles might glorify God for his mercy; as it is written, For this cause I will confess to thee among the Gentiles, and sing unto thy name. 10And again he saith, Rejoice, ye Gentiles, with his people. 11And again, Praise the Lord, all ye Gentiles; and laud him, all ye people. 12And again, Esaias saith, There shall be a root of Jesse, and he that shall rise to reign over the Gentiles; in him shall the Gentiles trust. 13Now the God of hope fill you with all joy and peace in believing, that ye may abound in hope, through the power of the Holy Ghost. 14And I myself also am persuaded of you, my brethren, that ye also are full of goodness, filled with all knowledge, able also to admonish one another. 15Nevertheless, brethren, I have written the more boldly unto you in some sort, as putting you in mind, because of the grace that is given to me of God, 16That I should be the minister of Jesus Christ to the Gentiles, ministering the gospel of God, that the offering up of the Gentiles might be acceptable, being sanctified by the Holy Ghost.

Matthew 12.38-45 (Gospel)

38Then certain of the scribes and of the Pharisees answered, saying, Master, we would see a sign from thee. 39But he answered and said unto them, An evil and adulterous generation seeketh after a sign; and there shall no sign be given to it, but the sign of the prophet Jonas: 40For as Jonas was three days and three nights in the whale’s belly; so shall the Son of man be three days and three nights in the heart of the earth. 41The men of Nineveh shall rise in judgment with this generation, and shall condemn it: because they repented at the preaching of Jonas; and, behold, a greater than Jonas is here. 42The queen of the south shall rise up in the judgment with this generation, and shall condemn it: for she came from the uttermost parts of the earth to hear the wisdom of Solomon; and, behold, a greater than Solomon is here. 43When the unclean spirit is gone out of a man, he walketh through dry places, seeking rest, and findeth none. 44Then he saith, I will return into my house from whence I came out; and when he is come, he findeth it empty, swept, and garnished. 45Then goeth he, and taketh with himself seven other spirits more wicked than himself, and they enter in and dwell there: and the last state of that man is worse than the first. Even so shall it be also unto this wicked generation.

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.
