"Buddhism is one of the many eastern religions that fits into Paul's description of those who 'changed the glory of the uncorruptible God into an image made like to corruptible man.... Who changed the truth of God into a lie, and worshipped and served the creature more than the Creator' (Romans 1:23,25)."
