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.)

47. And partaker in the affliction, signifies the truth of faith infested by falsities. This is evident from the signification of "partaker," as being the truth of faith (concerning which see below); and from the signification of "affliction," as being infestation by falsities (See Arcana Coelestia 6663, 1299, 6851, 9196). In the Word frequent mention is made of "brother" and "partaker" (or companion), and by these good and truth are signified. Moreover, in ancient times those were called "brethren" who were in good and those were called "partakers" (or companions) who were in truths, and for this reason, that truth must be in company with good, and when it is in company, it becomes a brother; consequently here by "partaker" is signified the truth of faith. (That good and truth are meant by "brother" and "companion" in the Word, see Arcana Coelestia 6756, 10490.) "Affliction" signifies infestation by falsities, since a mind that is in truths is afflicted by falsities, when the two are in conflict with each other; spiritual affliction is from no other source. This, therefore, is what is signified by "affliction" in the Word, as in Matthew:

He that was sown upon the rocky places hath no root in himself; when affliction and persecution ariseth because of the Word, straightway he is offended (Matthew 13:20-21).

And in the same:

In the consummation of the age they shall deliver you up into affliction. For then shall be great affliction, such as hath not been from the beginning of the world until now, 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 since falsities are then to prevail and fight against truths, it is said that they shall be in "affliction, and in so great a one as hath not been from the beginning of the world." Such affliction is meant by the affliction in which John is said to be a "partaker," and by John is here meant the doctrine respecting the Lord; for in Revelation the last time of the church is treated of (See above, n. 5).
