Romans 15:33

Now the God of peace be with you all. Amen--The peace here sought is to be taken in its widest sense: the peace of reconciliation to God, first, "through the blood of the everlasting covenant" (Heb 13:20; Th1 5:23; Th2 3:16; Phi 4:9); then the peace which that reconciliation diffuses among all the partakers of it (Co1 14:33; Co2 13:11; and see on Rom 16:20); more widely still, that peace which the children of God, in beautiful imitation of their Father in Heaven, are called and privileged to diffuse far and wide through this sin-distracted and divided world (Rom 12:18; Mat 5:9; Heb 12:14; Jam 3:18). Note, (1) Did "the chiefest of the apostles" apologize for writing to a Christian church which he had never seen, and a church that he was persuaded was above the need of it, save to "stir up their pure minds by way of remembrance" (Pe2 1:13; Pe2 3:1); and did he put even this upon the sole plea of apostolic responsibility (Rom 15:14-16)? What a contrast is thus presented to hierarchical pride, and in particular to the affected humility of the bishop of this very Rome! How close the bond which the one spirit draws between ministers and people--how wide the separation produced by the other! (2) There is in the Christian Church no real priesthood, and none but figurative sacrifices. Had it been otherwise, it is inconceivable that Rom 15:16 should have been expressed as it is.
