Things that Go Forth Therefrom Into the Mouth and Out of the Mouth

From  Apocalypse Explained ~ Emanuel Swedenborg

Not that which entereth into the mouth maketh the man unclean, but that which cometh out of the mouth, this maketh the man unclean. Whatsoever goeth into the mouth passeth into the belly, and is cast out into the draught. But the things that proceed out of the mouth come forth from the heart. Out of the heart go forth evil thoughts, murders, adulteries, fornications, thefts, false testimonies, blasphemies (Matthew 15:11, 17-19).

"That which entereth into the mouth" means in the literal sense food of every kind, which, after its use in the body, goes out through the belly into the draught; but in the spiritual sense, "that which entereth into the mouth" signifies all things that enter into the thought from the memory, and also from the world, and these also correspond to food; while the things that enter into the thought, and not also into the will, do not render a man unclean; for the memory, and thought therefrom, are to man only as a way of entrance to him, since the will is the man himself. The things that merely enter the thought and go no further are cast out as it were through the belly into the draught, "the belly" signifying from correspondence the world of spirits, from which thoughts flow in with man, and the "draught" signifying hell.

It must be known that man cannot be purified from evils and the consequent falsities, unless the unclean things that are in him come forth as far as into the thought, and are there seen, recognized, discerned, and put away. This makes evident that "that which entereth into the mouth" signifies in the spiritual sense what enters into the thought from the memory and from the world; while "that which cometh out of the mouth" signifies in the spiritual sense thought from the will or from love; for the "heart," from which thought goes forth into the mouth and from the mouth, signifies man's will and love; and as the love and will constitute the whole man, for the man is such as his love is, so the things that go forth therefrom into the mouth and out of the mouth are what make the man unclean. That these are evils of every kind is evident from the things enumerated. Such is the meaning of these words of the Lord in the heavens.

When the Sense of the Letter of the Word is delightful, but the Internal Sense Undelightful

From  Apocalypse Explained ~ Emanuel Swedenborg

And the voice which I heard from heaven again spake with me, and said, Go, take the little book that is open in the hand of the angel that standeth upon the sea and upon the earth. And I went unto the angel, saying unto him, Give me the little book. And he said unto me, Take and eat it up; and it shall make bitter thy belly, but in thy mouth it shall be sweet as honey. And I took the little book out of the hand of the angel and ate it up; and it was in my mouth like honey, sweet. And when I had eaten it my belly was made bitter.  (Revelation 10:8-10)

When the sense of the letter of the Word is delightful,
but the internal sense, in which are the truths themselves, it was undelightful.

It is to be known that the understanding of the Word perishes in the church by degrees, as the man of the church from internal becomes external; and from internal he becomes external as he falls away from charity, consequently as he falls away from the life of faith.

When the man of the church is such he may, indeed, take delight in reading the Word, but yet he takes no delight in the truth itself, which belongs to the interior sense of the Word; for it is the life itself of faith, which is charity, that produces the affection of interior truth and makes it delightful. Therefore the Word as to the sense of the letter may be loved, but for the reason that it can be drawn over to confirm the falsities arising from the love of self and of the world, for such is the Word in the letter.

From this it comes that in the end of the church there is scarcely any understanding of truth. Truths from the Word are indeed then spoken with the mouth, but yet there is no idea of truth. It has been granted me to test whether this is so in the case of many in the spiritual world, and it was found that although, so far as they had spoken from the Word they had spoken truths, yet they had no understanding of them; thus they were like empty vessels and like tinkling bells, speaking only from such things as they drew forth from the memory, and not at all from any perception of the understanding. When man is such he cannot inwardly possess anything celestial or spiritual, but only what is natural, from the body and the world, and when this is separated from what is celestial and spiritual it is infernal. From this it can be seen what is meant ... by the little book given to John to eat being in his mouth sweet as honey, but that his belly was made bitter from.

(Apocalypse Explained 614:2)

What Is Meant By Affection

From Arcana Coelestia ~ Emanuel Swedenborg

Affection is nothing else than love, but is what is continuous of it. For from love a man is affected either with evil and falsity, or with good and truth. As this love is present and is within all things in general and particular that belong to him, it is not perceived as love, but is varied according to its matter in hand, and according to the man's states and their changes; and this continually in everything that he wills, thinks, and does. It is this continuous of love that is called affection; and it is this continuous that reigns in a man's life and makes all his delight, and consequently his very life; for man's life is nothing else than the delight of his affection; and thus is nothing else than the affection of his love. Love is man's willing, and derivatively is his thinking, and thereby his acting.

(Arcana Coelestia 3938:8)
