I'm not good at names, but I found a website that has historical English religious words and names, so you can pick some and mix them together :D
clænnis (“cleanness, purity”), drihten (lord, the Lord – there are a lot of words like this), gastlic (“ghostly,” i.e. “spiritual”), gealga (“gallows,” now with the added meaning, “cross”) heofen (“heaven,” but originally just meaning “sky”), lar (“lore, teaching,” now also “doctrine”), woruld (“world,” ), wundor (“wonder, miracle”), and yfel (“evil.”) halig (“holy”), hell, geoffrian (“offer,” as in sacrifice), sawol (“soul”)
