“Hey! I understand that Paganism is an “umbrella” term as they say. But I’d like to know, if I believe that all things are part of the same whole or “God” classify as one or can be one? I don’t think that belief contradicts polytheism, just that any God/dess or being would be parts of this whole. And also, what are all the pagan symbols? I have Thor’s Hammer but I have no personal experience with him. Anything that’s just generally pagan?”
First I’d like to remind you that Paganism is not a form of religion or a set of beliefs. Instead, it is a set of “my own beliefs.” Modern Paganism is more of a philosophy of your own beliefs and practices – you make what you want of it. Its general practice is the belief in natural magick, nature, and energies of the Earth and Universe. Anything outside of that including the worship of a God or severals Gods, or the implementation of other religions or beliefs into that practice is all up to you.
In my own belief, the Universe is my “one” God. The Moon (Goddess) and the Sun (God) are aspects of the Universe and I see them “survival” energies for Earth and its inhabitants. All other gods act as “messengers” of the Universe and sometimes given certain abilities or gifts to control or give blessings over things; weather, harvest, health, birth, war, etc. So it’s really up to you on how you want to believe in deities, or even believe in them at all.
As far as symbols go; Thor’s Hammar isn’t necessarily Pagan, it’s Norse. But many Celtic Pagans/Wiccans use the symbol as part of their beliefs and practices. The general symbols of Paganism is obviously the Pentagram/Pentacle, among others like the Triquetra and the Triple Moon. A symbol Google search can be more elaborate.
