1 Corinthians 10.5-12 (Epistle)

5But with many of them God was not well pleased: for they were overthrown in the wilderness. 6Now these things were our examples, to the intent we should not lust after evil things, as they also lusted. 7Neither be ye idolaters, as were some of them; as it is written, The people sat down to eat and drink, and rose up to play. 8Neither let us commit fornication, as some of them committed, and fell in one day three and twenty thousand. 9Neither let us tempt Christ, as some of them also tempted, and were destroyed of serpents. 10Neither murmur ye, as some of them also murmured, and were destroyed of the destroyer. 11Now all these things happened unto them for ensamples: and they are written for our admonition, upon whom the ends of the world are come. 12Wherefore let him that thinketh he standeth take heed lest he fall.

Matthew 16.6-12 (Gospel)

6Then Jesus said unto them, Take heed and beware of the leaven of the Pharisees and of the Sadducees. 7And they reasoned among themselves, saying, It is because we have taken no bread. 8Which when Jesus perceived, he said unto them, O ye of little faith, why reason ye among yourselves, because ye have brought no bread? 9Do ye not yet understand, neither remember the five loaves of the five thousand, and how many baskets ye took up? 10Neither the seven loaves of the four thousand, and how many baskets ye took up? 11How is it that ye do not understand that I spake it not to you concerning bread, that ye should beware of the leaven of the Pharisees and of the Sadducees? 12Then understood they how that he bade them not beware of the leaven of bread, but of the doctrine of the Pharisees and of the Sadducees.

St Thomas of Mt Maleon (10th c.)

He was a renowned general, known for his great size and courage, his many victories against barbarian enemies, and his considerable wealth. But, forsaking wealth and reputation to follow Christ, he retired to the desert to live in asceticism. The Prophet Elias appeared to him and, accompanied by a pillar of fire, led him to Mount Maleon, near the Holy Mountain. There he lived in solitude, giving his days and nights to prayer. Like so many who seek to hide their holiness from the world, he was discovered, and people began to come to him for healing of their ailments and those of their loved ones. The saint healed countless ailments, drove out demons, cured the blind, and made water to pour forth from barren earth. In prayer he appeared as a pillar of fire. He reposed in peace, and his relics continued to be a powerful source of healing.

Holy Martyr Kyriake of Nicomedia (289)

Dorotheos and Eusebia, a devout, aging Christian couple who lived in Anatolia, had no children. After many years, their fervent prayers for a child were answered, and they were blessed with a daughter, whom they named Kyriake (‘Sunday’ in Greek) because she was born on the Lord’s day. The child grew up beautiful in body and soul and, though she had many suitors, chose to consecrate herself entirely to God and remain single. One of her suitors, angered at her refusal, denounced her and her parents to the Emperor Diocletian. Dorotheos and Eusebia were subjected to cruel tortures, then sent into exile, where they died under further torture. Kyriake was sent to Maximian, Diocletian’s son-in-law, for trial. By his orders, she was subjected to a horrifying series of torments; but Christ Himself appeared to her in prison, healing and comforting her. Many pagans came to believe in Christ when they saw her miraculously saved from death by fire or from wild beasts; all of these were beheaded. Kyriake told Apollonius, the general who supervised her tortures: ‘There is no way that you can turn me from my faith. Throw me into the fire — I have the example of the Three Children. Throw me to the wild beasts — I have the example of Daniel. Throw me into the sea — I have the example of Jonah the Prophet. Put me to the sword — I will remember the honored Forerunner. For me, to die is life in Christ.’ Apollonius then ordered that she be beheaded. At the place of execution, she raised her hands in prayer and gave up her soul to God before the executioner could take her life.

Note: St Kyriake is also known as Dominica or Nedelja, Latin and Slavonic words for ‘Sunday’.
