1 Corinthians 10.12-22 (Epistle)

12Wherefore let him that thinketh he standeth take heed lest he fall. 13There hath no temptation taken you but such as is common to man: but God is faithful, who will not suffer you to be tempted above that ye are able; but will with the temptation also make a way to escape, that ye may be able to bear it.

14Wherefore, my dearly beloved, flee from idolatry. 15I speak as to wise men; judge ye what I say. 16The cup of blessing which we bless, is it not the communion of the blood of Christ? The bread which we break, is it not the communion of the body of Christ? 17For we being many are one bread, and one body: for we are all partakers of that one bread. 18Behold Israel after the flesh: are not they which eat of the sacrifices partakers of the altar? 19What say I then? that the idol is any thing, or that which is offered in sacrifice to idols is any thing? 20But I say, that the things which the Gentiles sacrifice, they sacrifice to devils, and not to God: and I would not that ye should have fellowship with devils. 21Ye cannot drink the cup of the Lord, and the cup of devils: ye cannot be partakers of the Lord’s table, and of the table of devils. 22Do we provoke the Lord to jealousy? are we stronger than he?

Matthew 16.20-24 (Gospel)

20Then charged he his disciples that they should tell no man that he was Jesus the Christ.

21From that time forth began Jesus to shew unto his disciples, how that he must go unto Jerusalem, and suffer many things of the elders and chief priests and scribes, and be killed, and be raised again the third day. 22Then Peter took him, and began to rebuke him, saying, Be it far from thee, Lord: this shall not be unto thee. 23But he turned, and said unto Peter, Get thee behind me, Satan: thou art an offence unto me: for thou savourest not the things that be of God, but those that be of men.

24Then said Jesus unto his disciples, If any man will come after me, let him deny himself, and take up his cross, and follow me.

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.
