Acts 21:17 - Matthew Poole's English Annotations on the Holy Bible

It is thought, that by brethren in this place, and Acts 21:7, they are meant, who, being believers, were formed into a church with its several officers, and that they are called disciples only, Acts 21:4, who, living dispersed, and in smaller numbers, could not constitute such a church; but surely whatsoever there is of privilege and happiness in this spiritual fraternity, that truly catholic charity that was in the apostles and other holy men, would not so confine it, as to exelude any from enjoying of it, who did not exclude themselves by greater crimes than their paucity in number, or the consequences of that, could amount unto.
