A Portion of a Passage from Arcana Coelestia ~ Emanuel Swedenborg
[There are two things which are predicated of the Lord, namely, that He is King, and that He is Priest. A king, or the royalty, signifies the holy which is true; and a priest, or the priesthood, signifies the holy which is good; the former is the Divine spiritual, the latter the Divine celestial. The Lord as King governs each and all things in the universe from Divine truth; and as Priest, from Divine good. Divine truth is the very order of His universal kingdom, all the laws of which are truths, or eternal verities; Divine good is the very essential of order, all things of which are of mercy. Both of these are predicated of the Lord. If Divine truth alone were His, no mortal could be saved, for truths condemn everyone to hell; but Divine good, which is of mercy, uplifts from hell to heaven. These are what the kings and priests in the Jewish Church represented and these likewise Melchizedek represented, as king of Salem, and priest to God Most High. (Arcana Coelestia 1728)]
That the evil are nevertheless condemned to hell, is not because the Divine good is separated from the Divine truth, but because the man separates himself from the Divine good. For the Lord in no case sends anyone down into hell, but the man sends himself….
In the following respect also the Divine good is conjoined with the Divine truth: that unless the evil were separated from the good, the evil would do harm to the good, and would be continually endeavoring to destroy order: thus that the good may not be harmed, is of Mercy. This stands just as in the kingdoms of the earth. If evils were not punished, the whole kingdom would be infected with evils, and so would perish; for which reason kings and judges show more mercy in punishing evils and in expelling from society those guilty of them, than by exercising in their behalf an unseasonable clemency.
