You want the truth, that is found in the Catholic Church.
I respect that you think so but having studied long and hard and having spoken to many faithful and knowledgeable people (including priests), I just disagree.
Whatever "truth" the Roman Catholic church has remaining within it comes from Divinely-inspired Scripture and was believed all the way back to the original first Christians. The extraneous dogmas and doctrines added over the centuries that have perverted the gospel of the grace of God and which impose heavy burdens on souls never meant to be by God are NOT the truth from God. That is why those who diligently seek to know the truth WILL be rewarded by God and HE will lead them to the church home that best fits their needs. A church doesn't save - Jesus does.
