I'm thinking that could just be heartburn and not God, take some Maalox, study Catholicism and get back with us in a few years and tell us all you know and what we don't.
I suggest you seek the LORD independent of man's indoctrination. Read scripture and seek the LORD with all of your heart and you will find Him. All of life is about this. Maybe then, you too will know what it is like to have the truth burn in your heart.
