202. The Most Ancient Church, which was a celestial man, was of such a character as not only to abstain from "eating of the tree of knowledge" that is, from learning what belongs to faith from sensuous things and memory-knowledges [scientifica], but was not even allowed to touch that tree, that is, to think of anything that is a matter of faith from sensuous things and memory-knowledges, lest they should sink down from celestial life into spiritual life, and so on downward. Such also is the life of the celestial angels, the more interiorly celestial of whom do not even suffer faith to be named, nor anything whatever that partakes of what is spiritual; and if it is spoken of by others, instead of faith they have a perception of love, with a difference known only to themselves; thus whatever is of faith they derive from love and charity. Still less can they endure listening to any reasoning about faith, and least of all to anything of memory-knowledge [scientificum] respecting it; for, through love, they have a perception from the Lord of what is good and true; and from this perception they know instantly whether a thing is so, or is not so. Therefore when anything is said about faith, they answer simply that it is so, or that it is not so, because they perceive it from the Lord. This is what is signified by the Lord's words in Matthew:
Let your communication be Yea, yea; nay, nay; for whatsoever is more than these cometh of evil (Matt. 5:37).
This then is what was meant by their not being allowed to touch the fruit of the tree of knowledge; for if they touched it, they would be in evil, that is, they would in consequence "die." Nevertheless the celestial angels converse together on various subjects like the other angels, but in a celestial language, which is formed and derived from love, and is more ineffable than that of the spiritual angels.
