“Which is his body, the fulnesse of him that filleth all in all.”
1611 King James Version (KJV)
1:23 The fulness of him that filleth all in all - It is hard to say in what sense this can be spoken of the church; but the sense is easy and natural, if we refer it to Christ, who is the fulness of the Father.
Eph 1:23 Which is his body. His spiritual body, living by union with the Head, pervaded by the life of Christ. The fulness of him. The church is a manifestation of the fullness of Christ, the body filled by his life, who filleth all in all. Filleth all things with his majesty and power. The object of the last four verses is to describe Christ's glories. These are: (1) His resurrection; (2) His Exaltation to God's Right Hand; (3) His Supreme Dominion; (4) His Headship to the Church, his Body, filled with His Fullness. These glories all follow his stooping unto the death of the cross. He abased himself that he might be exalted. See Heb 12:2.
