1Be imitators of me, even as I also am of Christ.
2Now I praise you, brothers, that you remember me in all things, and hold firm the traditions, even as I delivered them to you. 3But I would have you know that the head of every man is Christ, and the head of the woman is man, and the head of Christ is God. 4Every man praying or prophesying, having his head covered, dishonors his head. 5But every woman praying or prophesying with her head uncovered dishonors her head. For it is one and the same thing as if she were shaved. 6For if a woman is not covered, let her hair also be cut off. But if it is shameful for a woman to have her hair cut off or be shaved, let her be covered. 7For a man indeed ought not to have his head covered, because he is the image and glory of God, but the woman is the glory of the man. 8For man is not from woman, but woman from man; 9for man wasn’t created for the woman, but woman for the man. 10For this cause the woman ought to have authority over her own head, because of the angels.
11Nevertheless, neither is the woman independent of the man, nor the man independent of the woman, in the Lord. 12For as woman came from man, so a man also comes through a woman; but all things are from God. 13Judge for yourselves. Is it appropriate that a woman pray to God unveiled? 14Doesn’t even nature itself teach you that if a man has long hair, it is a dishonor to him? 15But if a woman has long hair, it is a glory to her, for her hair is given to her for a covering. 16But if any man seems to be contentious, we have no such custom, neither do God’s assemblies.
17But in giving you this command I don’t praise you, because you come together not for the better but for the worse. 18For first of all, when you come together in the assembly, I hear that divisions exist among you, and I partly believe it. 19For there also must be factions among you, that those who are approved may be revealed among you. 20When therefore you assemble yourselves together, it is not the Lord’s supper that you eat. 21For in your eating each one takes his own supper first. One is hungry, and another is drunken. 22What, don’t you have houses to eat and to drink in? Or do you despise God’s assembly and put them to shame who don’t have enough? What shall I tell you? Shall I praise you? In this I don’t praise you.
23For I received from the Lord that which also I delivered to you, that the Lord Jesus on the night in which he was betrayed took bread. 24When he had given thanks, he broke it and said, “Take, eat. This is my body, which is broken for you. Do this in memory of me.” 25In the same way he also took the cup after supper, saying, “This cup is the new covenant in my blood. Do this, as often as you drink, in memory of me.” 26For as often as you eat this bread and drink this cup, you proclaim the Lord’s death until he comes.
27Therefore whoever eats this bread or drinks the Lord’s cup in a way unworthy of the Lord will be guilty of the body and the blood of the Lord. 28But let a man examine himself, and so let him eat of the bread and drink of the cup. 29For he who eats and drinks in an unworthy way eats and drinks judgment to himself if he doesn’t discern the Lord’s body. 30For this cause many among you are weak and sickly, and not a few sleep. 31For if we discerned ourselves, we wouldn’t be judged. 32But when we are judged, we are disciplined by the Lord, that we may not be condemned with the world. 33Therefore, my brothers, when you come together to eat, wait for one another. 34But if anyone is hungry, let him eat at home, lest your coming together be for judgment. The rest I will set in order whenever I come.
"Lord's" (Gk. κυριακῇ ἡμέρᾳ, kuriake hemera). (1:10; 1 Cor 11:20) Strong’s 2960
The word “Lord’s” occurs only twice in the NT, “day” is very common. The word “Lord’s” is used here for the “Lord’s day,” and in 1 Corinthians 11:20 it is used for the “Lord’s Supper.” It simply refers to that which belongs to and is associated with the Lord, Jesus Christ. The Lord’s Supper belongs to Him, is about Him and associates its participants with Him.
What of the Lord’s “Day?” First, it was a Sunday, associated with Jesus since it was the day of His resurrection, important in the life of the church from the beginning. Further, the day belongs to Jesus Christ and is about Him. John’s use of this term seems to identify Sunday as a day that is sacred and set aside for Jesus. This is not the Jewish Sabbath, but a celebration of the Lord’s resurrection and a dedication of the day to Him and His service. It is incumbent upon Christians to set aside Sundays for the Lord. Interestingly, some argue that the English word “church” comes from this Greek word for “Lord’s” through the Teutonic “kirk.”
