Arcana Coelestia #624
624. It is clear that a state which is not a state of the Church is the subject here from the fact that in this verse and those that follow in chapter the name God is used, whereas in previous verses it was Jehovah. When the Church does not exist the name God is used, but when it does exist, it is Jehovah; for example in Genesis 1, when the Church did not exist, He was called God, but in the next chapter when it did, He was called Jehovah God. 'Jehovah' is the holiest of names, and belongs to the Church alone. Not so 'God', for no nation was without gods. Consequently the same holiness was not attached to the name God. Nobody was allowed to utter the name Jehovah except him who had knowledge of the true faith; but anyone was allowed to utter the name God.

4792. Because food and nourishment correspond to spiritual food and nourishment, taste consequently corresponds to a perception of and an affection for this food. Spiritual food consists in knowledge, intelligence, and wisdom. These are what quicken and also sustain spirits and angels, who desire them and have an appetite for them as men desire and have an appetite for food when they are very hungry. Therefore appetite corresponds to that desire for them. And what is amazing, spirits and angels also grow to maturity on that spiritual food, for those who die as young children do not in the next life look like any but young children, and they are young children too as far as their understanding goes. But as they grow in intelligence and wisdom they cease to look like young children. They now look like those who are coming of age, and at length like adults. I have talked to some who died when they were young children and who looked to me like youths, for by then they had grown in understanding. From this one may see what spiritual food and nourishment are.
