John Calvin Commentary 1 Corinthians 12:26

"And whether one member suffereth, all the members suffer with it; or [one] member is honored, all the members rejoice with it." — 1 Corinthians 12:26 (ASV)

Whether one member suffers “Such a measure of fellow-feeling.” (συμπάθεια), says he, “is to be seen in the human body, that if any inconvenience is felt by any member, all the others grieve along with it, and, on the other hand, rejoice along with it, in its prosperity. Hence there is no room there for envy or contempt.” To be honored, here, is taken in a large sense, as meaning, to be in prosperity and happiness. Nothing, however, is better fitted to promote harmony than this community of interest, when every one feels that by the prosperity of others, he is proportionally enriched, and by their poverty, impoverished.
