Acts 4.1-10 (Epistle)

1And as they spake unto the people, the priests, and the captain of the temple, and the Sadducees, came upon them, 2Being grieved that they taught the people, and preached through Jesus the resurrection from the dead. 3And they laid hands on them, and put them in hold unto the next day: for it was now eventide. 4Howbeit many of them which heard the word believed; and the number of the men was about five thousand.

5And it came to pass on the morrow, that their rulers, and elders, and scribes, 6And Annas the high priest, and Caiaphas, and John, and Alexander, and as many as were of the kindred of the high priest, were gathered together at Jerusalem. 7And when they had set them in the midst, they asked, By what power, or by what name, have ye done this? 8Then Peter, filled with the Holy Ghost, said unto them, Ye rulers of the people, and elders of Israel, 9If we this day be examined of the good deed done to the impotent man, by what means he is made whole; 10Be it known unto you all, and to all the people of Israel, that by the name of Jesus Christ of Nazareth, whom ye crucified, whom God raised from the dead, even by him doth this man stand here before you whole.

John 3.16-21 (Gospel)

16For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life. 17For God sent not his Son into the world to condemn the world; but that the world through him might be saved.

18He that believeth on him is not condemned: but he that believeth not is condemned already, because he hath not believed in the name of the only begotten Son of God. 19And this is the condemnation, that light is come into the world, and men loved darkness rather than light, because their deeds were evil. 20For every one that doeth evil hateth the light, neither cometh to the light, lest his deeds should be reproved. 21But he that doeth truth cometh to the light, that his deeds may be made manifest, that they are wrought in God.

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.
