Jamieson, Fausset and Brown on 1 Corinthians 1:10

10. Now--Ye already have knowledge, utterance, and hope, maintain also love.

brethren--The very title is an argument for love.

by ... Christ--whom Paul wishes to be all in all to the Corinthians, and therefore names Him so often in this chapter.

speak ... same thing--not speaking different things as ye do (1Co 1:12), in a spirit of variance.

divisions--literally, "splits," "breaches."

but--"but rather."

perfectly joined together--the opposite word to "divisions." It is applied to healing a wound, or making whole a rent.

mind ... judgment--the view taken by the understanding, and the practical decision arrived at [Conybeare and Howson], as to what is to be done. The mind, within, refers to things to be believed: the judgment is displayed outwardly in things to be done [Bengel]. Disposition--opinion [Alford].
