Catholicity is a noun that refers to broadness or universality.
You may recognize the word ‘catholic’ in our word of the day. This is no coincidence. The Greek origin of the word ‘catholic’ had nothing to do with religion. Instead it meant ‘whole’ or ‘universal.’ Catholicity is the noun version of catholic.
I enjoyed my years at college, but I often wish I’d gotten a broader, more complete education. After all, when it comes to real world application, catholicity in one’s intelligence can be helpful.
