Your understanding (or lack thereof) of Catholic theology is pitiful, i.e. deserving of pity and sympathy.
Get a Catechism, or this book, which I highly recommend:
and find out the truth for yourself.
I'm a convert, and before I was a Catholic I heard all sorts of crazy stuff that people swore was Gospel truth. Thankfully I had the sense to go and find out for myself, instead of just believing the pulpit-thumpings of somebody with an axe to grind.
I wish I could understand the perverse pleasure Catholic-bashers take in savagely attacking things about which they know so little. Like a schoolyard bully, deep down inside they must feel very small, and this behavior somehow ameliorates their feelings of inadequacy.
