Metaphysical meaning of fish (rw)
fish--Represent ideas of multiplication and fecundity. Accounts in which Jesus figures as a party to fish eating are symbolical of the mental side of eating, which is the appropriation of ideas.
The reason Jesus so often used fish to illustrate His teaching is that He was a living demonstration of ideas, and all that He did was in the realm of ideas rather than in the realm of effects. Fish represent ideas in which there is great possibility of increase; Jesus used these ideas to represent the inexhaustible, everywhere present abundance.
