1 Corinthians 9.13-18 (Epistle)

13Do ye not know that they which minister about holy things live of the things of the temple? and they which wait at the altar are partakers with the altar? 14Even so hath the Lord ordained that they which preach the gospel should live of the gospel. 15But I have used none of these things: neither have I written these things, that it should be so done unto me: for it were better for me to die, than that any man should make my glorying void. 16For though I preach the gospel, I have nothing to glory of: for necessity is laid upon me; yea, woe is unto me, if I preach not the gospel! 17For if I do this thing willingly, I have a reward: but if against my will, a dispensation of the gospel is committed unto me. 18What is my reward then? Verily that, when I preach the gospel, I may make the gospel of Christ without charge, that I abuse not my power in the gospel.

Matthew 16.1-6 (Gospel)

1The Pharisees also with the Sadducees came, and tempting desired him that he would shew them a sign from heaven. 2He answered and said unto them, When it is evening, ye say, It will be fair weather: for the sky is red. 3And in the morning, It will be foul weather to day: for the sky is red and lowring. O ye hypocrites, ye can discern the face of the sky; but can ye not discern the signs of the times? 4A wicked and adulterous generation seeketh after a sign; and there shall no sign be given unto it, but the sign of the prophet Jonas. And he left them, and departed. 5And when his disciples were come to the other side, they had forgotten to take bread.

6Then Jesus said unto them, Take heed and beware of the leaven of the Pharisees and of the Sadducees.

Great-martyr Marina (Margaret) of Antioch in Pisidia (270)

She was born in Antioch of Pisidia to pagan parents; her father was a pagan priest. When she was about twelve years old her mother died, and she was given into the care of a woman who told her of the Gospel of Christ. She was immediately filled with love for Christ and consecrated her life to His service. Her father, hearing of this, was furious and disowned her. When she was fifteen years old, she was brought before the governor Olymbrius, who first desired to marry her and, when she refused, ordered her to make sacrifice to the idols. She refused and proclaimed herself a Christian. For this she was harshly tortured, imprisoned, and finally beheaded. While she was in prison she was tormented by demons, but drove them away by her prayers. For this reason she is especially invoked for deliverance from demonic possession. One of her hands is preserved at Vatopedi Monastery on the Holy Mountain, and some of her relics are preserved at an Albanian Monastery dedicated to her.
