Paganism
3
There's something about paganism that resonates in my celtic soul. Which shouldn't come as a big surprise, since Christianity borrowed over two thirds of its rituals from Celtic, Norse, Frankish, and Gothic paganism. They did it for the simple reason that it made conversion to Christianity simpler for pagans, not having to give up their familiar rituals.
Its highly amusing when folks with zero knowledge of history start talking about Christian traditions, when what they're really talking about are rituals meant to honor Odin, Mabd, and the rest of the polytheistic crew.
