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.)

356. And he that sat on him had a bow, signifies the doctrine of charity and faith from that understanding, by which evils and falsities are combated and dispersed. This is evident from the signification of "he that sat on a white horse," as meaning the Word (respecting which just above); also from the signification of "bow," as meaning the doctrine of charity and faith, by which evils and falsities are combated and dispersed. That "bow" signifies this doctrine will be seen in what follows. Here first let something be said respecting doctrine:

1. Without doctrine no one can understand the Word.

2. Without doctrine from the Word no one can fight against evils and falsities, and disperse them.

3. Without doctrine from the Word no one within the church, where the Word is, can become spiritual.

4. Doctrine can be acquired from no other source than from the Word, and by none except those who are in illustration from the Lord.

5. All things of doctrine must be confirmed by the sense of the letter of the Word.

In respect to the first, namely, "Without doctrine no one can understand the Word," it can be seen from this, that the sense of the letter consists of pure correspondences, which contain in themselves things spiritual, thus it consists of such things as are in the world and in its nature. From this it is that the sense of the letter is natural and not spiritual, accommodated, however, to the apprehension of the simple, who do not elevate their ideas above such things as they see before their eyes. From this it is, moreover, that it contains such things as do not appear to be spiritual, although the whole Word inwardly in itself is purely spiritual, because it is Divine. For this reason there are in the sense of the letter many things that cannot serve as doctrine for the church at this day, and many things that can be applied to various and diverse principles, and from this heresies arise; yet there are many things intermingled from which doctrine can be gathered and formed, especially the doctrine of life, which is the doctrine of charity and of faith therefrom. But he who reads the Word from doctrine sees there all things that confirm, as well as many things that lie concealed from the eyes of others; nor does he suffer himself to be drawn away into strange doctrines by those things in the Word that do not seem to agree, and that he does not understand; for all things of doctrine that he sees there are clear to him, and other things are obscure to him. Doctrine, therefore, which consists of genuine truths is as a lamp to those who read the Word; but on the other hand, to those who read the Word without doctrine it is like a lampstand without a light, placed in a dark place, by means of which nothing conducive to salvation can there be seen, known, inquired into, or found; moreover, one who so reads it is liable to be led away into any errors to which the mind is bent by some love, or is drawn by some principle. From this it can be seen that without doctrine no one can understand the Word.

[2] Second, "That without doctrine from the Word no one can fight against evils and falsities, and disperse them," can be seen from this, that from doctrine truths can be seen in their own light and in their own order, but not from the Word without doctrine. This is clear from what has just been said. But if truths cannot be seen, neither can falsities and evils be seen, for the latter are the opposite of the former; and yet all combat against evils and falsities is from truths, that is, by means of truths from the Lord; consequently he who reads the Word without doctrine may easily be led to fight for falsity against truth and for evil against good, by confirming evils and falsities by a wrong interpretation and application of the sense of the letter of the Word; and as a consequence the man is not reformed; for man is reformed by the dispersion of evils and the falsities of evil, by means of truths applied to the life. This is what is here meant by "the white horse" that was seen, and by "he that sat on him having a bow;" for "a white horse" signifies the understanding of truth from the Word, and "a bow" signifies the doctrine of charity and of faith therefrom by which evils and falsities are combated and dispersed.

[3] Third, "That without doctrine from the Word no one within the church, where the Word is, can become spiritual," can be seen from what has now been said, namely, that without doctrine the Word is not understood, and that without doctrine from the Word evils and falsities cannot be combated; for man becomes spiritual by means of a life according to Divine truths, which he does not know without doctrine, and by removing evils and falsities, which cannot be done without doctrine, as was said above. Without these two man is not reformed, thus does not become spiritual, but remains natural, and confirms his natural life by the sense of the letter of the Word, which is natural, by wrongly interpreting and applying it. It is said, within the church, where the Word is, since those who are out of the church do not have the Word, and therefore know nothing about the Lord; and no one becomes spiritual except from the Lord; and yet all who acknowledge a God and worship Him under the human form, and live in charity according to a religious principle that is in accord with the Word, are prepared by the Lord to receive spiritual life, and do receive it in the other life (on which we see in the work on Heaven and Hell 313-328; and above, n. 107, 195). Man becomes spiritual by regeneration, and regeneration is effected by "water and the spirit," that is, by means of truths and a life according to them (See in The Doctrine of the New Jerusalem, n. 173-186; that baptism in the Christian world is for a sign and memorial of regeneration, n. 202-209, in the same work).

[4] Fourth, "That doctrine can be acquired from no other source than from the Word, and by none except those who are in illustration from the Lord," can be seen from this, that the Word is Divine truth itself, and is such that the Lord is in it; for the Lord is in His Divine truth that proceeds from Him; those, therefore, who frame doctrine from any other source than from the Word, do not frame it from Divine truth nor from the Lord. Moreover, in the particulars of the Word there is a spiritual sense, and the angels of heaven are in that sense; consequently there is a conjunction of heaven with the church by means of the Word; those, therefore, who frame doctrine from any other source than the Word do not frame it in conjunction with heaven, from which nevertheless is all illustration. (That the conjunction of heaven with man is by means of the Word, see in the work on Heaven and Hell 303-310.) From this it is evident that doctrine is to be acquired from no other source than the Word, and by none except those who are in illustration from the Lord. They are in illustration from the Lord who love truths because they are truths; and because such as these do them, they are in the Lord and the Lord is in them.

[5] Fifth, "That all things of doctrine must be confirmed by the sense of the letter of the Word," can be seen from this, that Divine truth in the sense of the letter is in its fullness; for that is the ultimate sense, and the spiritual sense is in it; when, therefore, doctrine has been confirmed by that sense the doctrine of the church is also the doctrine of heaven, and there is conjunction by correspondence. Let this be illustrated by this only: when man thinks any truth and confirms it by the sense of the letter, it is perceived in heaven, but not if he does not confirm it; for the sense of the letter is the basis into which spiritual ideas, which are the angels' ideas, close, much the same as words are the basis into which the meaning of the thought falls and is communicated to another. That this is so might be confirmed by much experience from the spiritual world; but this is not the place to present it.
