Ephesians 4:16

by what every joint supplieth, &c. St. Paul compares the Church and mystical body of Christ (as he does elsewhere) to a natural body, whose perfection depends on the harmony, union, and concurrence of all the different parts; and so in the Church, of which Christ is the head, some are apostles, some prophets, &c. and Christ hath been pleased to give them different offices, talents, and gifts, for the edifying and increase of the whole body, which is his Church, that they may no longer be like Gentiles,...alienated from the life of God; from such a life as God requires they should lead. (Witham) --- The obscurity of this verse my be thus explained: the apostle compares the mystical body of the Church, of which Christ is the head, to the natural body of man; and as the head directs different members to different operations, according to their various properties, so in the Church Christ distributes to each his proper office, that being all intent upon their relative duties, all may grow up in charity and become perfect. (Estius)
