Charles Ellicott 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)

And whether one member suffer.—This verse completes the statement of the perfect unity of the members in one body and with one another. They are not only physically joined together, but they are so united as to feel together.
