"Emotion" probably isn't the best word. I cross-posted this comment on my Facebook account, where one person commented that
I agree, faith is not an emotion, just as love isn't. They are landscapes of experience which can be ornamented by a wide variety of emotions.
I'm not sure I agree with that entirely either, but it seems to be more in the right direction than just calling it an emotion is.
If it's worth saying, but not worth its own post, even in Discussion, it goes here.
