What's the difference, you may ask? Generally these terms are used interchangeably. Inevitably, when discussing paganism, one wonders about the nude/naked or skyclad rituals. I will be defining nude and naked as it relates to these rituals. Nude simply means without clothing. No embarrassment, just appearing in the state that you came into this world. Naked implies a sense of helplessness, embarrassment, and/or forced nudity. Skyclad is being nude outside.
I try to do my rituals nude when I can. It's part of loving my body with all its lumps and bumps and stretch marks. If you believe the bible, Adam and Eve were without clothes and unashamed of themselves before they "sinned". Pagans do not believe in original sin, so going nude is getting back to my roots, so to speak. Something about being nude is very freeing.
