226. All preachers are appointed by the Lord, and have therefrom a gift for preaching. No others are permitted to preach in the churches. They are not called priests, but preachers. They are not called priests because the celestial kingdom is the priesthood of heaven; for priesthood signifies the good of love to the Lord, and those in the celestial kingdom are in that good; while the spiritual kingdom is the kingship of heaven, for kingship signifies truth from good, and those in the spiritual kingdom are in that truth (see above, n. 24).#
# Priests represented the Lord in respect to the Divine good, kings in respect to Divine truth (n. 2015, 6148).
Therefore, in the Word a "priest" signifies those who are in the good of love to the Lord, and the priesthood signifies that good (n. 9806, 9809).
A "king" in the Word signifies those who are in Divine truth, and therefrom kingship signifies truth from good (n. 1672, 2015, 2069, 4575, 4581, 4966, 5044).
