Someone MAKES them do so?
Are they held at gunpoint?
I think they allow authority where none should be.
I assume that you believe that accepting Jesus as your Savior means you're saved. Does that mean you can sin as much as you want and still enter the Kingdom of Heaven?
Catholics believe that since God created us with free will, and He understood human beings, He also gave us the mechanism by which we could repent of our sins, on an ongoing basis. After all, if Jesus hadn't intended for us to repent of our sins, why did he give the Apostles the power to forgive them, in God's name? Jesus knew he was going to redeem us by His Saving Blood, yet he still allowed for Confession of our sins.
