Your post reminds me of a former catholic who now has full assurance of her salvation and is teaching others the Gospel Message as Jesus taught it.
She often shared some of the things she learned in catholicism and how she never felt she could live up to all the requirements...adding that she felt weighed down.
Look, there are some super fine catholic people out there. I know some, like some of my former catholic high school classmates. I have some friendly banter with a couple of them, but it is true, I also felt that no matter how I tried, I could not live up to their requirements. When I told a priest I could not do it, all he did, was tell me to lead a good life. You don't think that didn't frustrate me? Things are different now. 😇
