1-е Коринфянам 12:12

For as the body is one - Though the human body have many members, and though it be composed of a great variety of parts, yet it is but one entire system; every part and member being necessary to the integrity or completeness of the whole. So also is Christ - That is, So is the Church the body of Christ, being composed of the different officers already mentioned, and especially those enumerated, Co1 12:28, apostles, prophets, teachers, etc. It cannot be supposed that Christ is composed of many members, etc., and therefore the term Church must be understood, unless we suppose, which is not improbable, that the term Ὁ Χριστος, Christ, is used to express the Church, or whole body of Christian believers.

Unity, not unvarying uniformity, is the law of God in the world of grace, as in that of nature. As the many members of the body compose an organic whole and none can be dispensed with as needless, so those variously gifted by the Spirit, compose a spiritual organic whole, the body of Christ, into which all are baptized by the one Spirit. of that one body--Most of the oldest manuscripts omit "one." so also is Christ--that is, the whole Christ, the head and body. So Psa 18:50, "His anointed (Messiah or Christ), David (the antitypical David) and His seed."

For as the body is one,.... That is, an human body; for of this the apostle speaks, and takes a simile, and forms a comparison from, showing the union among saints, and their mutual participation of the various gifts of the Spirit; for an human body is but one body, and not more. And hath many members; as eyes, ears, hands, feet, &c. And all the members of that one body being many are one body; as numerous as they may be, they all belong to, and make up but one body; performing different offices, for which they are naturally fitted for the good of the whole: so also to Christ; not personal, but mystical; not the head alone, or the members by themselves, but head and members as constituting one body, the church. The church, in union with Christ, the head, is but one general assembly, and church of the firstborn written in heaven, though consisting of the various persons of God's elect, who are closely united one to another, and their head Christ; and therefore are denominated from him, and called by his name; see Rom 9:3.

The apostle here makes out the truth of what was above asserted, and puts the gifted men among the Corinthians in mind of their duty, by comparing the church of Christ to a human body. I. By telling us that one body may have many members, and that the many members of the same body make but one body (Co1 12:12): As the body is one, and hath many members, and all members of that one body, being many, are one body, so also is Christ; that is, Christ mystical, as divines commonly speak. Christ and his church making one body, as head and members, this body is made up of many parts or members, yet but one body; for all the members are baptized into the same body, and made to drink of the same Spirit, Co1 12:13. Jews and Gentiles, bond and free, are upon a level in this: all are baptized into the same body, and made partakers of the same Spirit. Christians become members of this body by baptism: they are baptized into one body. The outward rite is of divine institution, significant of the new birth, called therefore the washing of regeneration, Tit 3:5. But it is by the Spirit, by the renewing of the Holy Ghost, that we are made members of Christ's body. It is the Spirit's operation, signified by the outward administration, that makes us members. And by communion at the other ordinance we are sustained; but then it is not merely by drinking the wine, but by drinking into one Spirit. The outward administration is a means appointed of God for our participation in this great benefit; but it is baptism by the Spirit, it is internal renovation and drinking into one Spirit, partaking of his sanctifying influence from time to time, that makes us true members of Christ's body, and maintains our union with him. Being animated by one Spirit makes Christians one body. Note, All who have…

12:12-31 The church is like a body (see 12:27) composed of many different parts, each with its own function as determined by God (see 12:11, 18, 28; Rom 12:4-5).
