Just came across this article today.
THE REV. JOHN HELLER grew up in a Catholic family. When he got married, he and his wife attended Mass daily. Some of his co-workers encouraged him to check out their Pentecostal church. The first time they were there, Pastor LaFave preached a message about Mary and Martha, unbeknownst to him that was their favorite Bible story. He had never been in an annointed service like that, and it was when he had my Pentecostal experience. You can read the rest of the story here.
This is where poor catechesis ends.
No...It's where the bible begins...There are many well catechized former Catholics who came out of your religion to become born again Christians...If you would allow the Holy Spirit to speak to you thru the scriptures instead of you relying on your catechism, it would likely happen to you as well...
