Why does the word "Catholic" have two contrasting meanings?

catholic means including a wide variety of things; all-embracing.

and

Catholic means of the Roman Catholic faith.

But whenever I hear the someone say, "I'm catholic", it's hard for me to distinguish which usage are they referring to (even with the context). In writing, its easy to differentiate them by the lowercase/uppercase beginning.

My question, though, is what is the origin of the meaning of these two words? I get confused more because I associate the Catholicism with conservatism which is kinda the opposite of being catholic.


Solution 1:

I think the main religious usage is by far the more common, and the more general one can be easily understood in context. Note that in the religiosense the term is often capitalized:
