1 Peter 2:9

But ye are a chosen generation, a royal priesthood,— This imports them to be of one stock through their new birth; as the Israelites, who were by outward calling the chosen of God, were all the seed of Abraham according to the flesh: so theythat truly believe in the Lord Jesus, are all of them, by regeneration, one people. They are of one nation, belonging to the same blessed land of promise, all citizens of the new Jerusalem, yea, all children of the same family, whereof Jesus Christ, the root of Jesse, is the stock, who is the great King, and the great High-Priest. And thus they are a royal priesthood. There is no devolving of his royalty or priesthood on any other, as it is in himself; for his proper dignity is supreme and incommunicable, and there is no succession in his order; but they who are descended from him, do derive from him by that new original this double dignity, in that way in which they are capable of it, to be likewise kings and priests, as he is both.

An holy nation, &c.— "Ye are also a holy society formed into one spiritual body, like a nation collected together under Christ your Lord and King, sanctified by his Spirit, governed by his laws, and embarked in the same common cause and interest: and ye are a peculiar people, that, suitably to your dignities, privileges, blessings, and obligations, ye might both really and intentionally display the glory of divinevirtues and perfections; and might shew forth, in word and deed, his honour and praise, who has called you by his grace, and delivered you from the darkness of ignorance and error, sin and misery, in which you were formerly involved; and has brought you into the most wonderful and affecting lightof truth and grace, holiness and comfort, which he has caused to shine into your hearts: (2 Corinthians 4:6.)"
