(1Co 5:1-ff) It is actually reported that there is immorality among you, and immorality of such a kind as does not exist even among the Gentiles, that someone has his father's wife. You have become arrogant and have not mourned instead, so that the one who had done this deed would be removed from your midst. For I, on my part, though absent in body but present in spirit, have already judged him who has so committed this, as though I were present. In the name of our Lord Jesus, when you are assembled, and I with you in spirit, with the power of our Lord Jesus, I have decided to deliver such a one to Satan for the destruction of his flesh, so that his spirit may be saved in the day of the Lord Jesus.
Your boasting is not good. Do you not know that a little leaven leavens the whole lump of dough? Clean out the old leaven so that you may be a new lump, just as you are in fact unleavened. For Christ our Passover also has been sacrificed. Therefore let us celebrate the feast, not with old leaven, nor with the leaven of malice and wickedness, but with the unleavened bread of sincerity and truth.
I wrote you in my letter not to associate with immoral people; I did not at all mean with the immoral people of this world, or with the covetous and swindlers, or with idolaters, for then you would have to go out of the world. But actually, I wrote to you not to associate with any so-called brother if he is an immoral person, or covetous, or an idolater, or a reviler, or a drunkard, or a swindler--not even to eat with such a one. For what have I to do with judging outsiders? Do you not judge those who are within the church? But those who are outside, God judges. REMOVE THE WICKED MAN FROM AMONG YOURSELVES.
(1Co 9:7-15) Who at any time serves as a soldier at his own expense? Who plants a vineyard and does not eat the fruit of it? Or who tends a flock and does not use the milk of the flock? I am not speaking these things according to human judgment, am I? Or does not the Law also say these things? For it is written in the Law of Moses, "YOU SHALL NOT MUZZLE THE OX WHILE HE IS THRESHING." God is not concerned about oxen, is He? Or is He speaking altogether for our sake?
Yes, for our sake it was written, because the plowman ought to plow in hope, and the thresher to thresh in hope of sharing the crops. If we sowed spiritual things in you, is it too much if we reap material things from you? If others share the right over you, do we not more? Nevertheless, we did not use this right, but we endure all things so that we will cause no hindrance to the gospel of Christ.
Do you not know that those who perform sacred services eat the food of the temple, and those who attend regularly to the altar have their share from the altar? So also the Lord directed those who proclaim the gospel to get their living from the gospel. But I have used none of these things. And I am not writing these things so that it will be done so in my case; for it would be better for me to die than have any man make my boast an empty one.
