A cynic might suggest that if you are drawn to some b.astard offspring (and I use the term in its proper sense, not as an epithet) of paganism and Christianity, you could do worse than just convert to Roman Catholicism. It's all there in spades for you: a dying and rising god-king, a celestial goddess, highly stylised rites and rituals, rambling Latin incantations, offerings, minor deities governing various facets of life, candles and incense... heck, you even get to share most of the feast days.
