2144. 'In the oak-groves of Mamre' means the character of the perception. This is clear from the representation and meaning of 'oak-groves', and also from the representation and meaning of 'Mamre'. What oak-groves in general represented and meant has been shown in Volume One, in 1442, 1443, and what the oak-grove of Mamre specifically represented and meant, in 1616, namely perceptions, though of a human kind such as spring from factual knowledge and from the initial rational concepts derived from that knowledge.

[2] What perception is, is totally unknown at the present day, for nobody today possesses the kind of perception that the ancient and especially the most ancient people possessed. The latter knew from perception whether a thing was good and consequently whether it was true. There was an influx from the Lord by way of heaven into the rational part of their minds, and from that influx when they thought about anything holy, they perceived instantly whether a thing was so or was not so. Later on such perception with mankind perished and people began to entertain heavenly ideas no more but only worldly and bodily ones; and when this happened the place of such perception was taken by conscience (which also is a kind of perception), for acting contrary to conscience and according to conscience is nothing else than discerning from conscience whether a thing is so or not so, or whether it ought to be done.

[3] But perception that goes with conscience does not originate in inflowing good but in truth which from earliest childhood has been implanted in the rational part of the mind in accordance with the holiness of people's worship, and after that has been confirmed; for that truth alone is believed by them to be good. Consequently conscience is a kind of perception, but it has its origin in truth such as this; and when charity and innocence are introduced into it by the Lord, the good that goes with that conscience is then brought into being. These few considerations show what perception is. Yet between perception and conscience there is a wide difference. See what has been stated about perception in Volume One, in 104, 125, 371, 483, 495, 503, 521, 536, 597, 607, 784, 865, 895, 1121, 1616; about the perception spirits and angels have, in 202, 203, 1008, 1383, 1384, 1390-1392, 1394, 1397, 1504; and about the learned not knowing what perception is, in 1387.

[4] As regards the Lord when He lived in the world, all of His thought sprang from Divine perception since He alone was a Divine and Celestial Man. For He has been the only one in whom Jehovah Himself was present and from whom His perception came, also dealt with in Volume One, in 1616, 1791. His perceptions became more and more interior the closer He came to union with Jehovah. The nature of His perception at this time becomes clear from what has been stated in Volume One, in 1616, about the oak-groves of Mamre; and then the nature of it when He perceived the things contained in this chapter is described in what follows below.

202. The Most Ancient Church, which was celestial man, was not only forbidden to eat from the tree of knowledge, that is, to learn that which comprised faith from sensory evidence and from facts; it was not even allowed 'to touch that tree', that is, even to think from sensory evidence and from facts about anything that was a matter of faith. This was to prevent them slumping from celestial to spiritual life, and in this way going down further still. The life of celestial angels is also the same. Those of them who are more interiorly celestial do not even allow faith to be mentioned or anything whatever which has a spiritual origin. If others mention it they perceive love instead of faith, with a difference known only to themselves. Thus anything that is a matter of faith they derive from love and charity. Still less do they allow themselves to listen to anything of a rational nature concerning faith, and least of all to anything of a factual nature; for they possess from the Lord by way of love a perception of what good and truth are. From perception they know instantly whether something is so or not so. Consequently when any statement about faith is made their response is either That is so, or That is not so, for they are perceiving from the Lord. This is what the Lord's words mean in Matthew,

Let your words be, YES, YES, NO, NO; anything beyond this is from evil. ¹ Matthew 5:37.

The present verse in Genesis says that they were not allowed even to touch the fruit of the tree of knowledge, for if they did touch it, they would be subject to evil, that is, they would consequently die. All the same, celestial angels, like others, discuss various matters among themselves, but they do so in celestial language that is formed by, and derived from, love, a language that is more indescribable than the language of spiritual angels.

Fotnoter:

125. Verse 16 And Jehovah God commanded the man and said, From every tree in the garden you may indeed eat.

'Eating of every tree' is recognizing and knowing, from perception, what good and truth are; for, as stated already, 'a tree' means perception. Members of the Most Ancient Church possessed the cognitions of true faith by means of revelations, for they talked to the Lord and to angels. They were also taught through visions and dreams, which to them were supremely delightful and blissful. They received perception from the Lord continually; and as a result of that perception, when they thought from things in their memory they instantly perceived whether these were true and good, insomuch that when anything false came up they not only had nothing to do with it but were also horrified. This is also the state of angels. Later on however knowledge of what is true and good took the place of the perception which the Most Ancient Church enjoyed, a knowledge based on what had been previously revealed, and later, on things revealed in the Word.
