The verses included were less than the following, but for sake of clarity here are more:
1 Cor 12 says:
14Now the body is not made up of one part but of many. 15If the foot should say, "Because I am not a hand, I do not belong to the body," it would not for that reason cease to be part of the body. 16And if the ear should say, "Because I am not an eye, I do not belong to the body," it would not for that reason cease to be part of the body. 17If the whole body were an eye, where would the sense of hearing be? If the whole body were an ear, where would the sense of smell be? 18But in fact God has arranged the parts in the body, every one of them, just as he wanted them to be. 19If they were all one part, where would the body be? 20As it is, there are many parts, but one body.
21The eye cannot say to the hand, "I don't need you!" And the head cannot say to the feet, "I don't need you!" 22On the contrary, those parts of the body that seem to be weaker are indispensable, 23and the parts that we think are less honorable we treat with special honor. And the parts that are unpresentable are treated with special modesty, 24while our presentable parts need no special treatment. But God has combined the members of the body and has given greater honor to the parts that lacked it, 25so that there should be no division in the body, but that its parts should have equal concern for each other. 26If one part suffers, every part suffers with it; if one part is honored, every part rejoices with it.
27Now you are the body of Christ, and each one of you is a part of it.
It occurred to me how often I have heard this chapter preached at the door-minders, letter stuffers, dish washers, garbage handlers, and floor sweepers of the church by Ministers who delegate these positions of community-servanthood away from their busy schedule of sermonising. (I'll take this chance to exclude my current Pastor who does as good a job of trying to 'get it right' as I might hope for.)
I would be a fool not to concede that in any healthy community not everybody can perform identical roles at any one time. But the first-will-be-last/last-shall-be-first argument only holds so much water when so many Pastors seem, in reality, to use scripture to justify elevating themselves functionally to the top of the heap in their own little theocratic fiefdom.
Sick of washing dishes? Take heart, your work is indispensable! After all, should the eye say to the hand, "I don't need you"?
Want a shot at preaching? Sorry, but I mean, if the whole body were an ear, where would the sense of smell be? If we were all one part, where would the body be? You wouldn't want that, now would you?
When people do this subjugating theology with the contrasting biblical context being the highly ranked nature of Roman society it seems they don't quite so easily notice the replica Emperors in their own midst.
