This religion does indeed look a lot like Christianity, too much for my own tastes as well.
I've seen many monotheistic religions that did things differently. Torenism was indeed, one there's also
The Church of Teros, which while it burrowed many fundamental concepts, applied a different set of values, priorities, and vocabulary. That is, of course, before it got swallowed up by the Blood Cult and was rather streamlined to its autocratic warmongering.
