But that we may look more deeply into that grace which our inward man has in Christ, we must consider that in the Old Testament God sanctified to Himself every first-born male, and the birth-right was highly prized, having a two-fold honor, that of priesthood, and that of kingship. For the first-born brother was priest and lord over all the others, and was a type of Christ, the true and only First-born of God the Father and of the Virgin Mary, and true King and Priest, not after the fashion of the flesh and of the world. For His kingdom is not of this world [John 18:36]. He reigns in heavenly and spiritual things and consecrates them--such as righteousness, truth, wisdom, peace, salvation, etc. Not as if all things on earth and in hell were not also subject to Him--else how could He protect and save us from them?--but His kingdom consists neither in them nor of them. Nor does His priesthood consist in the outward splendor of robes and postures, like that human priesthood of Aaron and of our present-day Church; but it consists in spiritual things, through which He by an unseen service intercedes for us in heaven before God, there offers Himself as a sacrifice and does all things a priest should do, as Paul in the Epistle to the Hebrews describes him under the type of Melchizedek [Heb. 6 f.]. Nor does He only pray and intercede for us, but within our soul He teaches us through the living teaching of His Spirit, thus performing the two real unctions of a priest, of which the prayers and the preaching of human priests are visible types. Now, just as Christ by his birthright obtained these two prerogatives, so He imparts them to and shares them with every one who believes on Him according to the law of the aforesaid marriage, by which the wife owns whatever belongs to the husband. Hence we are all priests and kings in Christ, as many as believe on Christ, as I Pet. ii says, "Ye are a chosen generation, a peculiar people, a royal priesthood and priestly kingdom, that ye should show forth the virtues of Him Who hath called you out of darkness into His marvelous light." [1 Pet. 2:9] [Sidenote: The Kingship of the Christian]
