why not religionism ?

[Ferrocyanide]

Religionism: the strict practice of or devotion to religion
also, exaggerated religious zealotry

Religionist: a person adhering to a religion
especially, a religious zealot.

The word you're searching for, in that case, is "hilarious".

so it looks like the word is available but I haven't seen it used in that sense.
