10017. 'And the priesthood shall be theirs' means the stages, following one after another, of the Lord's work of salvation. This is clear from the meaning of 'the priesthood' or 'the priestly office' as that which is representative of the Lord's whole work of salvation, dealt with in 9809. The reason why the stages following one after another is meant is that the priesthood of Aaron's sons is the subject here, and his sons represent the things which emanate and so follow in order one after another, 9807. The situation in all this is that the priesthood which Aaron represents consists in the work of saving those who are in the Lord's celestial kingdom, this kingdom being the proper meaning in the Word of 'a kingdom of priests'. But the priesthood which Aaron's sons represent consists in the work of saving those who are in the Lord's spiritual kingdom emanating directly from His celestial kingdom. From this it is evident that 'the priesthood' is used in the present instance to mean the stages, following one after another, of the Lord's work of salvation. But the priesthood which the Levites represent consists in the Lord's work of salvation at a further stage.

[2] There are three realities which follow one another in order. These are the celestial, which is the good of love to the Lord; the spiritual, which is the good of charity towards the neighbour; and the natural springing from these, which is the good of faith. Since these three are realities which follow one another in order there are also three heavens, and in them the types of good follow in that order. The work of saving those with whom celestial good exists is represented by Aaron's priesthood; but the work of saving those with whom spiritual good exists is represented by the priesthood of Aaron's sons, and the work of saving those with whom the natural good springing from these exists is represented by the priesthood of the Levites. And since the things following one another in order emanate from the good of love to the Lord, which is represented by Aaron and his priesthood, it is said of the Levites that they were given to Aaron. For things which emanate belong to that from which they emanate; such emanations or stages following one after another owe their very existence to that source, as accords with what has been stated a little above in 10011. The fact that the Levites were given to Aaron and his sons to perform priestly duties under them, see Numbers 3:1-end.

48. Of the natural and the spiritual.

How perverse it is that the world at this day attributes so much to nature, and so little to the Divine (n. 3483). Why it is so (n. 5116). When nevertheless each and every particular in nature not only exists, but likewise continually subsists from the Divine, and through the spiritual world (n. 775, 8211). Divine, celestial, and spiritual things terminate in nature (n. 4240, 4939). Nature is the ultimate plane whereon they stand (n. 4240, 5651, 6275, 6284, 6299, 9216). Celestial, spiritual, and natural things follow and succeed each other in order; so do Divine things with them, because they are from the Divine (n. 880, 4938-4939, 9992, 10005, 10017, 10068). Celestial things are the head, spiritual things the body, and natural things the feet (n. 4938-4939). They also inflow in an order similar to that wherein they follow and succeed each other (n. 4938-4939).

The good of the inmost or third heaven is called celestial, the good of the middle or second heaven is called spiritual, and the good of the ultimate or first heaven is called spiritual natural, whence it may be known what is the celestial, spiritual, and natural (n. 4279, 4286, 4938-4939, 9992, 10005, 10017, 10068); and in 20-28, 29-40 in the work on Heaven and Hell.

All things of the natural world are from the Divine through the spiritual world (n. 5013). Consequently the spiritual is in every natural thing, just as the efficient cause is in the effect (n. 3562, 5711); or as effort is in motion (n. 5173), and as the internal is in the external (n. 3562, 5326, 5711). And since the cause is the very essential in the effect, as effort is in motion, and the internal in the external; hence it follows, that the spiritual, and consequently the Divine, is the very essential in the natural (n. 2987-3002, 9701-9709). Spiritual things are presented to view in the natural, and the things manifested are representatives and correspondences (n. 1632, 2987-3002). Hence all nature is a theater representative of the spiritual world, that is, of heaven (n. 2758, 2999-3000, 4939, 8848, 9280). All things in nature are disposed in order and series according to ends (n. 4104). This is from the spiritual world, that is, from heaven, because ends, which are uses, reign there (n. 454, 696, 1103, 3645, 4054, 7038). Man is so created that Divine things descending according to order into nature, may be perceived in him (n. 3702).

With every man, who is in Divine order, there is an internal and an external, his internal is called the spiritual, or the spiritual man, and his external is called the natural, or the natural man (n. 978, 1015, 4459, 6309, 9701-9709). The spiritual man is in the light of heaven, and the natural man in the light of the world (n. 5965). The natural man can discern nothing from himself, but from the spiritual (n. 5286). The natural is like a face in which the interiors see themselves, and thus man thinks (n. 5165). The spiritual man thinks in the natural, consequently naturally, so far as it comes to the sensual perception of the natural (n. 3679, 5165, 6284, 6299). The natural is the plane, in which the spiritual terminates (n. 5651, 6275, 6284, 6299, 9216). The spiritual sees nothing, unless the natural be in correspondence (n. 3493, 3620, 3623). The spiritual or internal man can see what is being done in the natural or external, but not the contrary, because the spiritual flows into the natural, and not the natural into the spiritual (n. 3219, 4667, 5119, 5259, 5427-5428, 5477, 6322, 9109-9110). The natural man from his own light, which is called the light [lumen] of nature, knows nothing concerning God, nor concerning heaven, nor concerning the life after death; neither does he believe, if he hears of such things, unless spiritual light, which is light from heaven, flows into that natural light [lumen] (n. 8944).

The natural man of himself, by birth, is opposite to the spiritual man (n. 3913, 3928). Therefore as long as they are opposite to each other, man feels it grievous to think of spiritual and celestial things, but delightful to think of natural and corporeal things (n. 4096). He nauseates the things of heaven, and even the bare mention of anything spiritual, from experience (n. 5006, 9109). Merely natural men regard spiritual good and truth as a servant (n. 5013, 5025). When nevertheless the natural man ought to be subordinate to the spiritual man, and serve him (n. 3019, 5168). The spiritual man is said to serve the natural, when the latter from the intellectual principle seeks confirmations of the objects of his concupiscence, particularly from the Word (n. 3019, 5013, 5025, 5168). How merely natural men appear in another life, and what is the quality of their state and lot there (n. 4630, 4633, 4940-4952, 5032, 5571).

The truths, which are in the natural man, are called scientifics and knowledges (n. 3293). The imagination of the natural man, when viewed in itself, is material, and his affections are like those of beasts (n. 3020). But there is a genuine thinking and imaginative principle from the internal or spiritual man, when the natural man sees, acts, and lives therefrom (n. 3493, 5422-5423, 5427-5428, 5477, 5510).

The things which are in the natural man, respectively to those which are in the spiritual man, are general (n. 3513, 5707); and consequently obscure (n. 6686).

There is an interior and an exterior natural with man (n. 3293-3294, 3793, 5118, 5126, 5497, 5649). There is also a medium between them (n. 4570, 9216). The discharges of the spiritual man are made into the natural, and by it (n. 9572).

They who do good merely from a natural disposition, and not from religion, are not received in heaven (n. 8002, 8772).
