1 Corinthians 2.9-3.8 (Epistle)

9But as it is written, Eye hath not seen, nor ear heard, neither have entered into the heart of man, the things which God hath prepared for them that love him. 10But God hath revealed them unto us by his Spirit: for the Spirit searcheth all things, yea, the deep things of God. 11For what man knoweth the things of a man, save the spirit of man which is in him? even so the things of God knoweth no man, but the Spirit of God. 12Now we have received, not the spirit of the world, but the spirit which is of God; that we might know the things that are freely given to us of God. 13Which things also we speak, not in the words which man’s wisdom teacheth, but which the Holy Ghost teacheth; comparing spiritual things with spiritual. 14But the natural man receiveth not the things of the Spirit of God: for they are foolishness unto him: neither can he know them, because they are spiritually discerned. 15But he that is spiritual judgeth all things, yet he himself is judged of no man. 16For who hath known the mind of the Lord, that he may instruct him? But we have the mind of Christ.

1And I, brethren, could not speak unto you as unto spiritual, but as unto carnal, even as unto babes in Christ. 2I have fed you with milk, and not with meat: for hitherto ye were not able to bear it, neither yet now are ye able.

3For ye are yet carnal: for whereas there is among you envying, and strife, and divisions, are ye not carnal, and walk as men? 4For while one saith, I am of Paul; and another, I am of Apollos; are ye not carnal? 5Who then is Paul, and who is Apollos, but ministers by whom ye believed, even as the Lord gave to every man? 6I have planted, Apollos watered; but God gave the increase. 7So then neither is he that planteth any thing, neither he that watereth; but God that giveth the increase. 8Now he that planteth and he that watereth are one: and every man shall receive his own reward according to his own labour.

Matthew 13.31-36 (Gospel)

31Another parable put he forth unto them, saying, The kingdom of heaven is like to a grain of mustard seed, which a man took, and sowed in his field: 32Which indeed is the least of all seeds: but when it is grown, it is the greatest among herbs, and becometh a tree, so that the birds of the air come and lodge in the branches thereof.

33Another parable spake he unto them; The kingdom of heaven is like unto leaven, which a woman took, and hid in three measures of meal, till the whole was leavened. 34All these things spake Jesus unto the multitude in parables; and without a parable spake he not unto them: 35That it might be fulfilled which was spoken by the prophet, saying, I will open my mouth in parables; I will utter things which have been kept secret from the foundation of the world. 36Then Jesus sent the multitude away, and went into the house: and his disciples came unto him, saying, Declare unto us the parable of the tares of the field.

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.
