:huh: No. The architecture of the "temples" in TESIV is strongly based on the cathedrals constructed in Europe, but the worship of the Eight-and-One Aedra is clearly polytheism.
EDIT: rings and white dresses are so booooooring. There are so many other cultures in the world, I imagine they handle things differently and more creatively.
I'm not sure where it's from but the Nine Divines are frequently called Polytheistic Catholic church. I share your sentiments though, there's got to be more interesting way.
Some people simply make their own vows and that it's. Something like:
I just wanna tell you how Im feeling
Gotta make you understand
Never gonna give you up
Never gonna let you down
Never gonna run around and desert you
Never gonna make you cry
Never gonna say goodbye
Never gonna tell a lie and hurt you
With Cyrodiils for Merchants and Aristocracy I'd imagine there be a bit more elaborate ceremony. Though looking up stuff, there is little variety even in the real thing. :S
