Hey. Yeah, I think I agree with Moody. I do think, though, that quite often beliefs can be informed by what has gone before. Some time in English history there were all kinds of fights between the Catholics and the protestents. In Ireland too. In those situations I guess protestants would take the wearing of a crucifix (with Jesus on it) as a symbol of catholic doctrine / dogma / belief and they wouldn't consider it fitting for a protestant.

Maybe your pastor has formed his beliefs along those lines...

Or maybe he thinks it is a symbol of Islam or something?

Could you ask him why he doesn't approve? Maybe if you discussed it he might change his mind? Perhaps?
