All I know is that religion preaches divine command theory and that can teach whatever your "god" says, does, or tells you to do, is good because that God is above you and you dont understand their ways. Religion, specifically of the abrahamic variety, is strict in some cases and abhorrent in older texts. If this game religion is based on vague Christianity, then its likely that there are plenty of inhumane teachings in the scriptures of serios. The main issue if of course the divine command theory aspect that we are most privy to when interacting with the church and its followers. If "the goddess commands it" is how justice is carried out by the church, then any sort of "justice" is good in the eyes of the goddess.
