" For many centuries Christians also believed in the idea of reincarnation, and it wasn’t until the Second Council of Constantinople in A.D. 553 that reincarnation was officially declared a heresy and mention of it was stricken from public texts. The powers that be didn’t like the idea of people getting infinite chances to get it right, because then you wouldn’t need the church to offer you salvation. "
