He isn't part of any religion. In The Deceived on the album Ascendancy, there are lyrics that say:
"Live by the former decrees, of a manufactured god." So by that I'd say he's atheist or agnostic.

He never really divulged into his philosophical or theological beliefs. I watched his interviews, listened to his songs, and watched his Twitch streams. If you want to go by lyrics I think it can give you some idea of what he believes but it won't give you the full details. So, I'm not really sure since he never really spoke on the topic.
