Of all believers with one another: _John 17:21_—“_that they may all be one_”; _1 Cor. 10:17_—“_we, who are many, are one bread, one body: for we all partake of the one bread_”; _Eph. 2:15_—“_create in himself of the two one new man, so making peace_”; _1 John 1:3_—“_that ye also may have fellowship with us: yea, and our fellowship is with the Father, and with his Son Jesus Christ_”—here the word κοινωνία is used. Fellowship with each other is the effect and result of the fellowship of each with God in Christ. Compare _John 10:16_—“_they shall become one flock, one shepherd_”; Westcott, Bib. Com., _in loco_: “The bond of fellowship is shown to lie in the common relation to one Lord.... Nothing is said of one ‘fold’ under the new dispensation.” Here is a unity, not of external organization, but of common life. Of this the visible church is the consequence and expression. But this communion is not limited to earth,—it is perpetuated beyond death: _1 Thess. 4:17_—“_so shall we ever be with the Lord_”; _Heb. 12:23_—“_to the general assembly and church of the firstborn who are enrolled in heaven, and to God the Judge of all, and to the spirits of just men made perfect_”; _Rev. 21_ and _22_—the city of God, the new Jerusalem, is the image of perfect society, as well as of intensity and fulness of life in Christ. The ordinances express the essence of Ecclesiology—union with Christ—for Baptism symbolizes the incorporation of the believer in Christ, while the Lord’s Supper symbolizes the incorporation of Christ in the believer. Christianity is a social matter, and the true Christian feels the need of being with and among his brethren. The Romans could not understand why “this new sect” must be holding meetings all the time—even daily meetings. Why could they not go singly, or in families, to the temples, and make offerings to their God, and then come away, as the pagans did? It was this meeting together which exposed them to persecution and martyrdom. It was the natural and inevitable expression of their union with Christ and so of their union with one another.
