My experience was that I really could not get "them" out if my head until I read Crisis of Conscience and In Search of Crhistian Freedom. both by Ray Franze. It was like a heave weight had been lifted from my shoulders, a weight I was not even aware that I was carrying.
The next "breakthrough" came after reading about Muhamid and then read a translation of the Koran. That stuff was all 'makeeupee" and caused me to look further into Biblical criticism. Put that all together along with my very own life experiences and my personal conclusion is that all "religion" is man made. The only book of the Bible worh reading is Ecclesiastes. Some interesting thoughts and ovservations there.
To sum up "religion"; it is all vanity and a striving after the wind.
For the first time I am enjoying the little things in life and valuing every day.
