The number one problem that the Catholic Church has is people who call themselves "Catholic" but don't believe. Usually they call themselves Catholic because their parents and grandparents were. They cause a lot of confusion and mislead other folks about Catholic beliefs.
I'll just hit the high spots - :-)
1. The Catholics that I know at work have the attitude that they can do anything they want (curse, lie, ect.) and just go confess it tomorrow and it will all be fine.
Nope. This is a sin called "presumption" - presuming on God's mercy in order to sin. It's worse than whatever the sin was in the first place . . . and will rate you a serious talking-to in the confessional if you own up to it (if you don't, it's still on your soul . . . a horrible thought).
2. Priests don’t have the authority to forgive anything.
Well, actually it is God who forgives. But He has given authority (through the laying on of hands by the successors to the Apostles, who received the authority from Christ himself) to His priests to give penance and absolution in His name: "Whose soever sins ye remit, they are remitted unto them; and whose soever sins ye retain, they are retained." John 20:23.
3. I’m Catholic and we don’t know anything about the Bible
See citation above - I also suspect she was pulling your leg. We hear virtually the entire Bible (except the 'begats' and some of the chronicle books) through in 3 years, thanks to 2 scripture readings + Psalm in every daily Mass, and 3 on Sundays. And if you ever get a chance to attend an Easter Vigil (what you would probably call a Watchnight Service), you will hear a dozen or more scripture readings, with Psalms to match (and antiphons, that is to say chanted scripture, in between).
4. You probably won't see nuns, because they are cloistered. While you might see sisters, you wouldn't necessarily know it because many of them have abandoned their habits. This, in my not particularly humble opinion, was a bad and stupid thing. Hence the recent Vatican investigation of the noisy and radical feminist group of sisters called LCWR . . . like I said, it's folks calling themselves Catholics but believing no such thing that do the most damage to the Church.
. . . just a little old convert here from the wilds of North Georgia . . . :-D
Thanks so much for your comments. I replied to Carpe Cerevisi and forgot to ping you. My comments also were meant for you as explanation of my thoughts.
