"For the body does not consist of one member but of many." (1 Corinthians 12:14)
Paul's whole argument about the body is not that we are alike. Read it again; it is the opposite argument, a long and almost comic insistence that we are not alike, and that the not-being-alike is the entire point. If the whole body were an eye, where would the hearing be? If the whole body were an ear, where would the sense of smell be? He is asking us to picture a giant eyeball rolling around, and to consider whether we would like to belong to that church.
And then he says a thing that ought to end a great many arguments. The parts of the body that seem to be weaker are indispensable. Not tolerable. Not to be patiently endured. Indispensable. The person in your church you find hardest to be around, the one whose presence in a meeting makes your jaw tighten, is not an obstacle to the body. Paul says they may well be a vital organ.
That is not a nice sentiment; it is an anatomy lesson, and it should sober us. You cannot remove the parts that annoy you and still have a body, any more than you can remove the parts of yourself that are inconvenient and still be alive. The difficult member is not the church's problem to manage around. They may be the organ the whole body cannot live without. So before you route around someone, ask whether you have just decided a lung is optional.
