The technical sin in almost all religions, not just Catholic, is the sex outside of marriage.
Using the line "obviously this means they're not religious" means 99% of the people in the world are "not religious" if they're following a bible based religion.
Also all religions have their people who only show up on holidays or funerals
I doubt Piggy is religious and is using the excuse of being catholic to bail her ass out.
Sweeping generalizations are what pisses people off
I agree with your first statement, it's a sin in all religions. I'm not sure if you can ask for forgiveness in all of them though. I know you can with the Catholic religion.
Your second statement, I can agree with you maybe I worded it wrong. I don't think it's a yes or no kind of thing though. Going to place of worship doesn't make you religious. But people who are religious tend to go all the time. But that too doesn't prove that you are religious. For me personally, I'm not religious I was not brought up learning about my religion and my father asked for my forgiveness for not teaching me our religion. I forgave him. I told him I believe there is a God and I told him my philosophy. So I'm not necessarily atheist.
Being religious is a state of mind. And that last statement I just wrote is actually true.
I do agree with you for Priscilla to say that she's Catholic to try to cover up what she did. I believe she is not religious.
The last statement, I'm not trying for blanket statements, I am going generally towards the Maass family. I have no problem taking criticism, admitting that I'm wrong, no one is ever right all the time. My stepmom used to only go to Church only during Christmas and Easter, after my father died she goes every week. And she's very religious now. My dad was very religious, but after his first divorce he wasn't and we stopped being kosher and only practiced the Jewish holidays. This is just life, and people are able to choose if they want to be religious or not, so no, I was definitely not going for blanket statements. I hope you understand. And no, I wasn't trying to piss anyone off or offend anyone.
