If I don't think certain parts of this faith are valid...?

Very very valid. I have always wondered this myself. Also I have wondered why in my town of about 2500 people do we have like 9 christian churches and 6 are Baptist at least. When Jesus walked the earth he brought everyone to one central place, all who would hear and spoke. Not to a fancy building with people of your choosing or that you like or who had the best band or most charismatic preacher. If a man walked by and hear his words it didn't matter of what creed he was, he was welcomed to hear. Nowadays its a task just to find a church to go to by standards when truly if everyone came together as a whole it would most likely be beneficial. No fancy building or band or high tech electronics or bathing pool needed. My opinion.
