It’s hard for me to really comment on those appendant bodies because I’m not a member of them. I do know members of the Scottish Rite and and they’ve never indicated to me that there was any in sort of religious instruction. I think the York Rite would be much more likely to have that kind of content than the Scottish Rite.
I recently read a couple of articles on the York Rite and was soon lost in all the variations. To me, even as ignorant as I am, it seems obvious that generalizing about Freemasonry is a tricky path.
