366. That they should slay one another, signifies the falsification or extinction of truths. This is evident from the signification of "slaying," as meaning the extinction of truths; for "to slay" in the Word signifies to slay spiritually, that is, to slay the spiritual part of a man or his soul, which is to extinguish truths. It also means to falsify, because when truths are falsified they are also extinguished; for falsification produces a different understanding of truths, and truth is true to everyone according to his understanding of it; for the love and principle that rule in man draw and apply all things to themselves, even truths themselves; consequently when the love is evil, or the principle is false, then truths are infected with the evil of the love or the falsity of the principle, and thus are extinguished. This, therefore, is what is here signified by "they should slay one another." That this takes place when there is no good with man, and especially when there is no good in the doctrine of his church, is evident from the preceding words, where it is said, "When he had opened the second seal there went forth a red horse; and to him that sat upon him it was given to take peace from the earth;" which signifies a second state of the church when the understanding of the Word is destroyed in respect to good, which is the source of dissensions in the church (of which see above, n. 361, 364, 365).

[2] That the understanding of the Word, or what is the same, the understanding of the truth, is destroyed when there is no good with man, that is, when there is no love to the Lord and charity towards the neighbor, may be seen above n. 365; for good with man, or what is the same, love with him, is the fire of his life, and truth with him, or the faith of truth, is the light therefrom; consequently such as the good is, or such as the love is in man, such is truth, or such the faith of truth in him. From this it can be seen that when evil or an evil love is with man there can be no truth or faith of truth with him; for the light that goes forth from such fire is the light that those have who are in hell, which is a fatuous light like the light from burning coals, which light, when light from heaven flows in, is turned into mere thick darkness. Such also is the light that with the evil, when they reason against the things of the church, is called natural light [lumen].

[3] That they would falsify and thereby extinguish truths is meant also by the Lord's words in Matthew:

Jesus said to the disciples, The brother shall deliver up the brother, the father the son; children shall rise up against parents, and cause them to be put to death (Matthew 10:21).

And in Luke:

Ye shall be delivered up by parents, and brethren, and kinsfolk, and friends; and some of you shall they cause to be put to death (Luke 21:16).

"Parents," "brethren," "children," ["kinsfolk, "] and "friends," do not mean here parents, brethren, children, kinsfolk, friends, nor do "disciples" mean disciples, but the goods and truths of the church, also evils and falsities; it is also meant that evils would extinguish goods and falsities truths. (That such is the signification of these words, see Arcana Coelestia 10490.)

29. And the Prince of the kings of the earth, signifies from whom is all the truth from good in the church. This is evident from the signification of "Prince of kings," as meaning from whom is all truth; a "prince" denoting what is primary, and "kings" truths; and, because it refers to the Lord, who is here called "Prince of kings," it means from whom is all truth (that "prince" means what is primary, see Arcana Coelestia 1482, 2089, 5044; and that "kings" are truths, see in the explanation of the following verse, where it is said, "and hath made us kings and priests," n. 31; also from the signification of the "earth," as meaning the church (of which in what follows). One who knows not the internal sense of the Word must needs believe that the kings of the whole earth are here meant; whereas kings are not meant, nor earth; but by "kings" are meant all who are in truths from good; and by the "earth" is meant the church. (That by the "earth" is signified the church is shown in many places in the Arcana Coelestia, from which these particulars may be seen: That by the "earth" is signified the kingdom of the Lord and the church, n. 662, 1066, 1068, 1262, 1413, 2928, 3355, 4447, 4535, 5577, 8011, 9325, 9643. The chief reason of which is, that by the "earth" is meant the land of Canaan; and the church was there from most ancient times, n. 567, 3686, 4447, 4454, 4516, 4517, 5136, 6516, 9325, 9327; also that, in the spiritual sense, by the "earth" is meant the nation who dwell thereon, and their worship, n . 1262. That the "new heaven the new earth" signify the church in the heavens on earth 1733, 1850, 2117, 2118, 3355, 4535, 10373. That by the creation of heaven and earth, in the first chapters of Genesis, in the internal sense, is described the establishment of the Most Ancient Church, see n. 8891, 9942, 10545. That to "create" is to establish and regenerate, see n. Arcana Coelestia 10373. That "ground," too, signifies the church; "ground" from the reception of seeds, which are truths, but "earth" from the nations therein, and their worship, see n. 566, 1068, 10570. Moreover, "earth," as it signifies the church, signifies also the religious principle, consequently also such as is idolatrous; as the land of Egypt, the land of the Philistines, the land of Chaldea, and of Babel, and many others. That "earth" signifies the church is also briefly shown in the small work on The Last Judgment 3, 4.)
