This one is heavy. First, a little background. I am the son of an Episcopal Priest. Because of this, I grew up in church, and because of my curiosity, I was always reading the Bible, or any theology that came my way. I wanted to know what in this collection of books (BIBLIA means a collection of separate books, hence our Bible) was the source for the seemingly infinite variety of denominations and sects that claimed to be following the teachings of Jesus the Christ. In all my study as a youth, and in the decades since, I have never found any of what Jesus the Christ taught, preached, or espoused, to be complex. His teachings are exceedingly basic, and applicable to all humans in all lands. The many religions/sects/cults (they are all the same thing) that sprung up in Jesus’ wake, however, have conflated his teachings, and obscured the simple message behind walls of ritual, baroque language, and the seemingly impenetrable man-made creation of the priesthood. The worst one seems to be the Roman Catholic Church.
