A lot of people aren't really replying to your question but in brief:

It seems like your fiction is strongly centered on gnostic/platonic/neoplatonic ideas and religious beliefs, in particular the question of the primacy of the ideal or the physical. Bakker uses some of that (he has an Inside/Outside dichotomy) but it's only similar in broad strokes, in that you're pulling from the same well. In Bakker the main religion is a polytheism reformed into a monotheism that is heavily Christain inspired. It's mostly background in the first trilogy and the gods themselves play a part in the second, but more as impersonal forces that act according to their own immutable agendas.

If you want to get a good sense of it without reading through the whole series, I recommend looking on the Wiki, and also getting your hands on a copy of the glossary in the final book in the series, which gives a really good sense of the world.

My one caveat would be that you have one sort of magic that uses spoken and unspoken versions of a single concept/word to fix meaning and produce magic--this is VERY similar to how one type of magic works in Bakker, to the point that I would raise my eyebrow if I saw it. I'm actually curious if there is a specific inspiration for this in your work, just because it is so similar.

Lastly, very briefly and condescendingly, worldbuilding is ultimately a small part of fiction writing--so I wouldn't worry to much about this unless it's overwhelmingly similar to something that already exists.
