I'm sorry, but that is simply not Catholic doctrine. In fact, you are risking eternal damnation by spouting heresy.
Then I should tell our Father Pastor at my Catholic Church that he is wrong thinking believing in the Father, the Son, and the Holy Ghost, saves a person, gives a person eternal life.
He has been a Priest for many years. Before becoming a Priest, he was a sniper in our military. When hunting season comes around, he's out there with the guys hunting.
There is always a church barbecue during hunting season, and he makes barbecue if he has hunting success, which he always does. He says he has a new barbecue grill for this year.
I just love it when the properly catechized Catholics and the Poorly catechized ones go head-to-head!
