Ephesians 4:16

From whom the whole body fitly joined gether
By which is meant, the church; see ( Ephesians 1:23 ) sometimes it designs all the elect of God in heaven and in earth, but here the church militant, which only can admit of an increase; this body is from Christ, as an head, and the phrase denotes the rise and origin of the church from Christ, her dependence upon him, and union to him, and of its members one to another; she has her being and form, from him, and all her blessings, as her life and light, righteousness and holiness, her grace and strength, her joy, peace, and comfort, her fruitfulness and final perseverance; and her dependence is upon him for subsistence, sustenance, protection and safety, and for grace and glory; and her union to him is very near, strict and close, and indissoluble; and the union between the several members is also very close, and both are very beautiful:

and compacted by that which every joint supplieth, according to the
effectual working in the measure of every part.
The Alexandrian copy reads, "of every member"; and so the Vulgate Latin, Syriac, and Arabic versions; the author of the union of the members of Christ's body to one another is the Spirit of God, by him they are baptized into one body; the cement or bond of this union is the grace of love wrought in their souls by him; and the means are the word and ordinances, and these convey a supply from Christ the head to every member, suitable to the part it bears in the body, according to the energy of the Spirit, who makes all effectual: and so

maketh increase of the body unto the edifying of itself in love;
the increase of the body the church, is either in numbers, when persons are converted and added to it; or in the exercise of grace, under the influence of the Spirit, through the ministration of the word and ordinances; and both these tend to the edifying or building of it up; and nothing is of a more edifying nature to the church than love, which bears the infirmities of the weak, and seeks for, and follows after those things which make for peace and godly edification, ( 1 Corinthians 8:1 ) .
