'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.
