I am not Catholic and I know Catholicism is a false religion. It is no surprise to me that you didn't find the truth, and I am pretty sure from what you have said you did not find a good Bible teacher in the Catholic Church.I was a hardcore Catholic for 35 years. I understood the gospel mentally but I wasn't able to really feel its goodness. I didn't even I was unconsciously trying to get this feeling of goodness by reading the gospel. A part of me longed to connect the source of this goodness. Reading the bible worked occasionally but it didn't compare to the omni-present version of goodness that comes from deep within each and every one of us. It was the same thing with the feeling of richness. I tried to get it from money but now I see the feeling of richness comes from the soul too. The soul is a miracle and it supplies us with all our needs in the exact dosage and at the precise time it is needed. It is one with infinite intelligence. Expect nothing less. It contains the truest versions of qualities such as compassion, benevolence, serenity, love, grace, strength, peace, joy. The excellence of these attributes are on another order.
Don't get me wrong. The traditional version of Christianity is important too. I wouldn't be where I am without it so I am grateful. I just had an experience that allowed me to move on to a higher understanding. We will all get the same thing eventually, it's just a matter of time. I do suggest doing whatever is necessary to do the work of having the experience now while we are alive, however. It makes life so much more meaningful. It's really a wonderful thing. I can't stop giving praise and glory to God even if I wanted to. I know for a fact that once you feel it you won't be able to either.
I recommend studying the gospel. If you have never heard what I am talking about or if you want you should look at 1 Corinthians 15:1-8, Romans 3:23, 6:23, Ephesians 2:8-9, and Titus 3:5. This is about the forgiveness of sins and the free gift of eternal life in Jesus Christ.
