“And has put all things under his feet, and gave him to be the head over all things to the church, which is his body, the fullness of him that fills all in all.”
~ Eph 1:22-23
In the mind of God, and as chosen in Christ, the Church is a perfect body. It is, therefore, the fullness of Christ. Just as our head and members, in their union with each other, form one perfect harmonious body, so it is with Christ and the Church. As the natural head would be incomplete without the body, as the body would be incomplete without the head, so it is with Christ mystical, and his body the Church. Each needs the other, and the union of both makes the whole complete.
The Son of God, by becoming incarnate, needed a body of which he should be the Head. Without it, he would be as a bridegroom without the bride, a shepherd without the sheep, a foundation without the building, a vine without the branches. He did not need the Church as the Son of God, but he needed her as the Son of man. In her all his love is complete, his work complete, his grace complete, his glory complete; and when she is brought home to be forever with him in glory, then all the purposes of God, all his eternal counsels of wisdom and grace, will be complete. In this sense we may understand the expression, “the fullness of him that fills all in all.” What a wonderful thought it is that he who, as the Son of God, fills all in all ~ fills all places with his omnipresence ~ should yet stoop to have a relative fullness in his body the Church!
