The modern use of the word Paganism is an umbrella term that may include everything from Asatru (worship of Norse gods) to Hellenic (worship of Greek gods) traditions. The word pagan usually refers to an individual who has a polytheistic faith; that’s, a religion that features more than one god or goddess. The word had the connotation of unsophisticated, or country dweller.
I think as being polytheistic, frequently nature based magic practitioners who aren’t bound by the Wiccan Rede of modern pagans and practice a faith that is not Christianity, Judaism, or Islam. Each group of gods and goddesses has rules that are distinct, after all.
Wicca, by contrast, is a brand new religion, originating just fifty or sixty years back. A lot of Wiccan traditions step away from history thoroughly, although it’s partly based on what earlier generations may have practised.
Wiccans usually observe holidays based on seasonal changes, Sabbats and Esbats. These celebrations as a whole are generally referred to as the Wheel of the Year. Other terms that differentiate Wicca from Paganism are the Rede and also the Rule of Three. The most crucial portion of the Rede is the oft-quoted a it harm none, do what thou wilt, while the Rule of Three is a karmic law that says that all actions of the witch will represent on him or her with three fold results, whether positive or negative.
There in many cases are differences in the rituals each subset practices while Wicca may be contained under the umbrella of paganism. Among the more important differences between pagans and Wicca is that a certain group within Paganism gives much time and energy to reconstruction. This is actually the study of how ancestral peoples practiced those religions that have survived in a single form or another with the goal of keeping modern practice true to first customs as possible, into the modern age. Therefore, Hellenic, Celtic, Khemtic and other customs based on location can have rites that are different from Wiccan, or indeed other pagans.
Just keep in mind that wherever you go to practice, the rites will vary substantially (occasionally by tremendous degrees). It’s important to embrace just the practices which you feel comfortable with in any pagan rite. Since there are so many different forms of practice, you really should understand what you are getting into before embarking on a journey of practising folks, in almost any new group. I understand that it took me a very long time to find folks I was comfortable with.
