1442. 'As far as the oak-grove of Moreh' means a first perception. This too becomes clear from the sequence of events. It is clear that as soon as Jehovah appeared to the Lord in His celestial things the Lord had attained perception. Celestial things are the source of all perception. What perception is has been stated and shown already in 104, 202, 371, 483, 495, 503, 521, 536, 865. When anyone attains to celestial things he acquires perception from the Lord. All who have become celestial people, such as members of the Most Ancient Church, have acquired perception, as shown already in 125, 597, 607, 784, 895. All who become spiritual people, however, that is, who acquire charity from the Lord, have something akin to perception, namely the voice of conscience, strong or weak, in the measure that the celestial things of charity exist with such persons. This is how it is with the celestial things of charity, for it is in these alone that the Lord is present, and in these that He manifests Himself to man. How much more must this have applied to the Lord, who from infancy moved closer to Jehovah, and was joined and united to Him so that they were one?

483. The names which follow - Seth, Enosh, Kenan, Mahalalel, Jared, Enoch, Methuselah, Lamech, and Noah - mean just so many Churches, the first and chief one of which was called Man. The chief characteristic of these Churches was perception, and therefore the differences between the Churches of that period were primarily differences in perception. On the subject of perception, let it be mentioned here that nothing else reigns in the whole of heaven but the perception of good and truth. Its nature defies description, and includes differences so countless that no one community's perception is exactly like that found in another. Perceptions there fall into genera and species. Those genera are countless, and so too are the species within every genus. These in the Lord's Divine mercy will be dealt with later on. Since there are countless genera, and countless species within every genus, and even more countless sub-species to each species, it becomes clear how very little indeed the world of today knows about celestial and spiritual matters. It does not even know what perception is, and if told, it does not believe that it even exists. The same applies to other matters too.

[2] The Most Ancient Church represented the Lord's celestial kingdom, even as to each variation of perception in its genus and species. But because nobody nowadays knows what perception is, not even the most general aspect of it, facts of a wholly strange and meaningless nature would therefore be imparted if the genera and species of the perceptions of those Churches were stated. They were divided into houses, families, and nations, and used to contract marriages within their own houses and families, in order that genera and species of perception might be established and be derived from parents altogether as reproductions of innate dispositions. This also is why members of the Most Ancient Church dwell together in heaven.
