Charles Spurgeon Commentary 1 Corinthians 11:18

"For first of all, when ye come together in the church, I hear that divisions exist among you; and I partly believe it." — 1 Corinthians 11:18 (ASV)

For first of all, when ye come together in the church, I hear that there be divisions among you; and I partly believe it.

It was very gracious and kind on the apostle's part to put it so mildly, and he sets us the example of not believing anything against our brothers too quickly: I partly believe it.
