Jesus Christ hath made us kings and priests (Rev. 1:6);

and likewise:

The Lamb hath made us kings and priests, that we may reign over the earth (Rev. 5:10). And it may be clearly seen that the Lord will not make men kings and priests, but that He will make them angels who are in the truths of wisdom, and in the good of love from Him. That by "kings" are meant they who are in the truths of wisdom from the Lord, and that the Lord is called "king" from the Divine truth, may be seen above (n. 20, 483, 664, 830). The reason why by "priests" are meant those who are in the good of love from the Lord, is because the Lord is the Divine love and the Divine wisdom, or what is the same, the Divine good and the Divine truth; and the Lord from the Divine love or the Divine good, is called "priest," and from the Divine wisdom or the Divine truth, is called "king." Hence it is, that there are two kingdoms, into which the heavens are distinguished, the celestial and the spiritual; and the celestial kingdom is called the Lord's priestly kingdom, for the angels there are recipients of the Divine love or the Divine good from the Lord, and the spiritual kingdom is called the Lord's royal kingdom, for the angels there are the recipients of the Divine wisdom or the Divine truth from the Lord; but more may be seen concerning these two kingdoms above (n. 647, 725). [2] It is said that they are recipients of the Divine good and the Divine truth from the Lord; but it is to be known that they are perpetually receiving them, for the Divine good and the Divine truth cannot be appropriated by any angel or man, so as to be his own, but only that they may appear to be his, because they are Divine; wherefore no angel or man can produce from himself anything good or true, which in itself is good and true; from which it is evident that they are kept in good and truth by the Lord, and this continually; for which reason, if anyone comes into heaven, and thinks that good and truth are appropriated to him as his own, he is immediately let down from heaven and instructed. From these things it may now appear, that by "they shall be priests of God and of Christ," is signified because they were kept by the Lord in the good of love, and thereby in the truths of wisdom. [3] That by priests in the Word are meant such as are in the good of love from the Lord, may appear from many passages therein, but as they are adduced in the Arcana Coelestia published at London, I will only quote therefrom the following: "That priests represented the Lord as to the Divine good (n. 2015, 6148). That the priesthood was a representative of the Lord as to the work of salvation, because this was from the Divine good of His Divine love (n. 9809) That the priesthood of Aaron, of his sons, and of the Levites, was a representative of the Lord's work of salvation in successive order (n. 10,017). That therefore by "priests" and by "the priesthood" is signified the good of love from the Lord (n. 9806, 9809). That by the two names, "Jesus" and "Christ," is signified as well the priesthood as the royalty of the Lord (n. 3004, 3005, 3009). That priests administer ecclesiastical affairs, and kings civil affairs (n. 10,793). That priests are to teach truths, and by these lead to good, and thus to the Lord (n. 10,794). That they are not to claim power to themselves over the souls of men (n. 10,795). That priests ought to have dignity on account of holy things, but that they ought not to attribute the dignity to themselves, but to the Lord, from whom alone are holy things, because the priesthood is not in the person, but is adjoined to the person (n. 10,796, 10,797). That priests who do not acknowledge the Lord have in the Word a contrary signification (n. 3670).
