If others be partakers.... — You do recognise this principle in regard to other teachers, and they actually partake of this right to be supported by you; we, your first teachers, have a stronger right. St. Paul had been literally their “planter” (1 Corinthians 3:6).
But suffer all things — i.e., We endure all kinds of hard work and privation rather than use a power which I have demonstrated we possess, and which others actually avail themselves of, lest our doing so might, in a way, hinder the progress of Christ’s gospel by giving enemies any even apparent reason for attributing our zeal to unworthy motives.
