'Mean' in the Bible

Now I mean this, that each one of you says, “I am [a disciple] of Paul,” or “I am [a disciple] of Apollos,” or “I am [a disciple] of Cephas (Peter),” or “I am [a disciple] of Christ.”

Now as to the matters of which you wrote: It is good (beneficial, advantageous) for a man not to touch a woman [outside marriage].

But I say this, believers: the time has been shortened, so that from now on even those who have wives should be as though they did not;

Is the cup of blessing which we bless [at the Lord’s Supper] not a sharing in the blood of Christ? [Indeed it is.] Is the bread which we break not a sharing in the body of Christ? [Indeed it is.]

and by conscience I mean for the sake of the other man’s, not yours. For why is my freedom [of choice] judged by another’s conscience [another’s ethics—another’s sense of right and wrong]?

What! Do you not have houses in which to eat and drink? Or do you show contempt for the church of God and humiliate those [impoverished believers] who have nothing? What will I say to you? Shall I praise you for this? In this I will not praise you!

Otherwise, what will those do who are being baptized for the dead? If the dead are not raised at all, why are people even baptized for them?
