1 Corinthians 14.6-19 (Epistle)

6Now, brethren, if I come unto you speaking with tongues, what shall I profit you, except I shall speak to you either by revelation, or by knowledge, or by prophesying, or by doctrine? 7And even things without life giving sound, whether pipe or harp, except they give a distinction in the sounds, how shall it be known what is piped or harped? 8For if the trumpet give an uncertain sound, who shall prepare himself to the battle? 9So likewise ye, except ye utter by the tongue words easy to be understood, how shall it be known what is spoken? for ye shall speak into the air. 10There are, it may be, so many kinds of voices in the world, and none of them is without signification. 11Therefore if I know not the meaning of the voice, I shall be unto him that speaketh a barbarian, and he that speaketh shall be a barbarian unto me. 12Even so ye, forasmuch as ye are zealous of spiritual gifts, seek that ye may excel to the edifying of the church. 13Wherefore let him that speaketh in an unknown tongue pray that he may interpret. 14For if I pray in an unknown tongue, my spirit prayeth, but my understanding is unfruitful. 15What is it then? I will pray with the spirit, and I will pray with the understanding also: I will sing with the spirit, and I will sing with the understanding also. 16Else when thou shalt bless with the spirit, how shall he that occupieth the room of the unlearned say Amen at thy giving of thanks, seeing he understandeth not what thou sayest? 17For thou verily givest thanks well, but the other is not edified. 18I thank my God, I speak with tongues more than ye all: 19Yet in the church I had rather speak five words with my understanding, that by my voice I might teach others also, than ten thousand words in an unknown tongue.

Matthew 20.17-28 (Gospel)

17And Jesus going up to Jerusalem took the twelve disciples apart in the way, and said unto them, 18Behold, we go up to Jerusalem; and the Son of man shall be betrayed unto the chief priests and unto the scribes, and they shall condemn him to death, 19And shall deliver him to the Gentiles to mock, and to scourge, and to crucify him: and the third day he shall rise again.

20Then came to him the mother of Zebedee’s children with her sons, worshipping him, and desiring a certain thing of him. 21And he said unto her, What wilt thou? She saith unto him, Grant that these my two sons may sit, the one on thy right hand, and the other on the left, in thy kingdom. 22But Jesus answered and said, Ye know not what ye ask. Are ye able to drink of the cup that I shall drink of, and to be baptized with the baptism that I am baptized with? They say unto him, We are able. 23And he saith unto them, Ye shall drink indeed of my cup, and be baptized with the baptism that I am baptized with: but to sit on my right hand, and on my left, is not mine to give, but it shall be given to them for whom it is prepared of my Father. 24And when the ten heard it, they were moved with indignation against the two brethren. 25But Jesus called them unto him, and said, Ye know that the princes of the Gentiles exercise dominion over them, and they that are great exercise authority upon them. 26But it shall not be so among you: but whosoever will be great among you, let him be your minister; 27And whosoever will be chief among you, let him be your servant: 28Even as the Son of man came not to be ministered unto, but to minister, and to give his life a ransom for many.

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.
