We have much to learn from our Brothers and Sisters in Christ.  I recall my own childhood when I lived in terror of dying with a mortal sin on my soul.  The nuns dutifully told us how important it was to receive forgiveness through the words of absolution from a priest.  It all seemed so mechanical to me.  We also knew that those people, unfortunate enough to belong to another Church (all heretical) would be condemned to hell, no matter how exemplary the lives they lived.  On one hand, there is a loving God who loves us, cares for us, and wants heaven for us, but on the other hand, that same God would send people to hell because they belonged to the wrong club.  What if our own parents were Lutheran, or Reformed, or belonged to any other Church?  We would be condemned simply because we took the faith of our parents.  

Our individual theology was skewed to justify our observance of the "right" way.  Many people leave the RCC because they are disillusioned with their childhood Church.
