Thematic Bible: Who is divided

For you are still [unspiritual, having the nature] of the flesh [under the control of ordinary impulses]. For as long as [there are] envying and jealousy and wrangling and factions among you, are you not unspiritual and of the flesh, behaving yourselves after a human standard and like mere (unchanged) men? For when one says, I belong to Paul, and another, I belong to Apollos, are you not [proving yourselves] ordinary (unchanged) men? What then is Apollos? What is Paul? Ministering servants [not heads of parties] through whom you believed, even as the Lord appointed to each his task: read more.
I planted, Apollos watered, but God [all the while] was making it grow and [He] gave the increase. So neither he who plants is anything nor he who waters, but [only] God Who makes it grow and become greater. He who plants and he who waters are equal (one in aim, of the same importance and esteem), yet each shall receive his own reward (wages), according to his own labor. For we are fellow workmen (joint promoters, laborers together) with and for God; you are God's garden and vineyard and field under cultivation, [you are] God's building.

But in what I instruct [you] next I do not commend [you], because when you meet together, it is not for the better but for the worse. For in the first place, when you assemble as a congregation, I hear that there are cliques (divisions and factions) among you; and I in part believe it, For doubtless there have to be factions or parties among you in order that they who are genuine and of approved fitness may become evident and plainly recognized among you. read more.
So when you gather for your meetings, it is not the supper instituted by the Lord that you eat, For in eating each one [hurries] to get his own supper first [not waiting for the poor], and one goes hungry while another gets drunk.
