Acts 15.35-41 (Epistle)

35Paul also and Barnabas continued in Antioch, teaching and preaching the word of the Lord, with many others also.

36And some days after Paul said unto Barnabas, Let us go again and visit our brethren in every city where we have preached the word of the Lord, and see how they do. 37And Barnabas determined to take with them John, whose surname was Mark. 38But Paul thought not good to take him with them, who departed from them from Pamphylia, and went not with them to the work. 39And the contention was so sharp between them, that they departed asunder one from the other: and so Barnabas took Mark, and sailed unto Cyprus; 40And Paul chose Silas, and departed, being recommended by the brethren unto the grace of God. 41And he went through Syria and Cilicia, confirming the churches.

John 10.27-38 (Gospel)

27My sheep hear my voice, and I know them, and they follow me: 28And I give unto them eternal life; and they shall never perish, neither shall any man pluck them out of my hand. 29My Father, which gave them me, is greater than all; and no man is able to pluck them out of my Father’s hand. 30I and my Father are one. 31Then the Jews took up stones again to stone him. 32Jesus answered them, Many good works have I shewed you from my Father; for which of those works do ye stone me? 33The Jews answered him, saying, For a good work we stone thee not; but for blasphemy; and because that thou, being a man, makest thyself God. 34Jesus answered them, Is it not written in your law, I said, Ye are gods? 35If he called them gods, unto whom the word of God came, and the scripture cannot be broken; 36Say ye of him, whom the Father hath sanctified, and sent into the world, Thou blasphemest; because I said, I am the Son of God? 37If I do not the works of my Father, believe me not. 38But if I do, though ye believe not me, believe the works: that ye may know, and believe, that the Father is in me, and I in him.

St Athanasius the Great, Patr. of Alexandria

His main commemoration is January 18.

Holy Martyrs Hesperus, his wife Zoë, and their sons Cyriac and Theodulus (2nd c.)

Early in the second century a pagan named Catallus bought Hesperus, his wife Zoë, and their sons Cyriac and Theodulus as slaves. All of them were Christians, and would not eat anything that had been sacrificed to idols — they would throw all such food to the dogs and go hungry themselves. When Catallus learned of this, he was enraged and began to torture them cruelly, beginning with the children. When none of them could be moved from his confession of Christ, the entire family was cast into a hot furnace, where they gave up their souls to God. Their bodies remained unburnt.

Holy Tsar Boris-Michael of Bulgaria (907)

A son of the Bulgarian Khan Presian, he was instructed in the faith by St Photios, Patriarch of Constantinople. He labored throughout his reign to establish and spread the Christian faith in Bulgaria. When the disciples of Ss Cyril and Methodius were driven from Moravia and came to Bulgaria, he greatly assisted them in their missionary work there. He retired to a monastery, leaving rule of his country in the hands of his son Vladimir. But when he learned that Vladimir was persecuting Christians and trying to re-establish paganism, he left the monastery, took up the sword, overthrew his son, put his younger son Symeon on the throne and, when he was confident that the country was again in Christian hands, returned to the monastery, where he ended his life in peace and piety.
