Ah hah! A true rebel, I like that! (LOL). I will say at the outset here, and in all seriousness, that I do indeed respect your belief's concerning your Christian faith journey.
And who came up with those sacraments, those holy things designed to help us live a holy and pleasing life for God? Why no one other than God Himself!
Yes, that is true and the Catholic Church teaches that. But you also have your clergy, an ordained person who exists to lead you in your walk with God and you call him your "Pastor". We also have our ordained person and call him a "Priest". They are both shepherds of their flock here on earth, no?
Well, we Catholics and our Eastern Orthodox brothers beg to differ with you here and we do not run afoul of the scriptures you cited earlier.
I'm not seeing any unnecessary baggage. There is a lot of liberty in the Catholic faith tradition and other than the core beliefs that must be adhered to, the individual is free to not believe or participate in many other things that exist within it's walls.
