Well, friend, if we are going to discuss what a metaphor is and is not, we need a definition. I pointed out simply that because it was a metaphor, you could not make a complete comparison on additional details.
If you could rightly do this, than Christ claiming to be the Bread of Life could mean so many more things that what He actually meant.
(Scratching the old coconut meditatively.) But I didn’t see anybody who was actually misunderstanding what a metaphor is. However, a good definition is always welcome, so thank you.
