366. That they should kill one another. That this signifies the falsification or extinction of truths, is manifest from the signification of killing, as denoting to extinguish truths; for by killing in the Word is signified to kill spiritually, or to kill the spiritual part of man or his soul, which is to extinguish truths. The reason why it also denotes to falsify, is, because when truths are falsified, they are also extinguished; for by falsification a different understanding of them is arrived at, and truth is truth according to the understanding of any one concerning it; for the love and the principle which have rule in man, draw and apply all things to them, even truths themselves; wherefore, when the love is evil, or the principle false, then the truths are infected with the evil of the love, or the falsity of the principle, and so are extinguished; this therefore is what is here signified by, "that they should kill 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 manifest from the preceding words, where it is said: "When he had opened the second seal, there went out a red horse; and it was given to him that sat thereon to take peace from the earth"; by which is signified a second state of the church, when the understanding of the Word is destroyed as to good, whence divisions arise in the church (concerning which see above, n. 361, 364, 365).

[2] That the understanding of the Word, or, what is the same, the understanding of truth, is destroyed when there is no good with man, that is, where there is no love to the Lord and charity towards the neighbour, may be seen above (n. 365); for good in man, or what is the same, love in him, is the fire of his life, and truth in him, or the faith of truth, is the light thence; therefore according to the quality of the good or the quality of the love in him, such is the truth, or the faith of truth in him. Hence it is evident that if man is in evil, or in an evil love, he cannot be in the truth, or in the faith of truth; for the quality of the light which issues from that fire, is light to those who are in hell, which is a fatuous light, like the light from burning coals, which light is turned into mere darkness from the light flowing in from heaven. Such also is the light called natural light (lumen) with the evil, when they reason against the things of the church.

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

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

And in Luke:

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

By parents, brethren, children, [kinsfolk,] and friends, are not meant here parents, brethren, children, kinsfolk, friends, nor by disciples are meant disciples, but the goods and truths of the church, also evils and falsities; and that evils will extinguish goods, and falsities truths. (That such things are signified by these names, see the Arcana Coelestia 10490.)

47. And companion in affliction. That this signifies, the truth of faith infested by falsities, is evident from the signification of companion, as being the truth of faith - see what follows; and from the signification of affliction, as denoting infestation by falsities (concerning which see Arcana Coelestia 6663, 6851, 9196). In the Word mention is frequently made of brother and companion, and by them good and truth are signified; in ancient times also, those were called brethren who were in good, and companions those who were in truth. The reason of this is that truth must be conjoined with good, and when it is so, it becomes a brother; this is why companion here signifies the truth of faith. (That good and truth are meant by brother and companion in the Word, may be seen, Arcana Coelestia 6756, 10490.) The reason why affliction signifies infestation by falsities is, because the mind which is in truths is afflicted by falsities, when they fight with each other, nor does spiritual affliction spring from any other source. This then is the signification of affliction in the Word, as in Matthew:

"He that received the seed upon stony places hath no root in himself, but when affliction and persecution ariseth because of the Word, immediately he is offended" (13:20, 21).

And in the same:

In the consummation of the age: "they shall deliver you up to affliction, and then shall be great affliction, such as was not from the beginning of the world to this time, no, nor shall be. Immediately after the affliction of those days the sun shall be darkened" (Matthew 24:9, 21, 29; Mark 13:19, 24).

The consummation of the age is the last time of the church; and because falsities would then reign and fight against truths, therefore it is said that they shall be in affliction, and so great as was not from the beginning of the world. This is what is meant by the affliction in which John is said to be a companion, by whom is here meant doctrine concerning the Lord; for in the Apocalypse the last time of the church is treated of (see above, n. 5).
