1 Corinthians 12:12-18, 22-27

For just as the body is one and yet has many parts, and all the parts, though many, form [only] one body, so it is with Christ. For by one [Holy] Spirit we were all baptized into one body, [spiritually transformed—united together] whether Jews or Greeks (Gentiles), slaves or free, and we were all made to drink of one [Holy] Spirit [since the same Holy Spirit fills each life]. [Rom 3:22; Gal 3:28] For the [human] body does not consist of one part, but of many [limbs and organs]. If the foot says, “Because I am not a hand, I am not a part of the body,” is it not on the contrary still a part of the body? If the ear says, “Because I am not an eye, I am not a part of the body,” is it not on the contrary still a part of the body? 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? But now [as things really are], God has placed and arranged the parts in the body, each one of them, just as He willed and saw fit [with the best balance of function].

But quite the contrary, the parts of the body that seem to be weaker are [absolutely] necessary; and as for those parts of the body which we consider less honorable, these we treat with greater honor; and our less presentable parts are treated with greater modesty, while our more presentable parts do not require it. But God has combined the [whole] body, giving greater honor to that part which lacks it, so that there would be no division or discord in the body [that is, lack of adaptation of the parts to each other], but that the parts may have the same concern for one another. And if one member suffers, all the parts share the suffering; if one member is honored, all rejoice with it. Now you [collectively] are Christ’s body, and individually [you are] members of it [each with his own special purpose and function].
