My personal beliefs on deity are as many-faceted as most religions and the gods they all worship. When it comes down to it, I don't know anything, I can only go by what I feel is right for me. What feels right to me is that there is a Oneness that created Them.
Personally, I do believe in gods and goddesses and I believe in MANY such gods and goddesses.
However, I also believe that man created the gods, not the other way around. So yes, there are many gods and goddesses and they may or may not be one and the same.
I honor many and all gods and goddesses because I feel as if they are deserving of my respect; someone somewhere at some point in history honored and revered them, and therefore that makes them as real as anything else.
