Looking a page that goes right into a rudimentary Gospel message for people unfamiliar with any faith, yet is still Catholic. Most of the stuff here is great but is designed for answering Protestant objections.
I like CatholicsComeHome.org
Right on the front page, they have three “doors” to go through depending on where you’re at. And each door further has two or three sub-statements to narrow things down further.
It sounds like you’re looking for “I’m not really religious” under the “I’m not Catholic” door.
That will serve. Thanks.
