Undiluted Is Best

Please don’t judge Christianity as a whole by American Christianity. While there are multitudes of wonderful Christians here, there are millions of what the Bible calls “tares” (wheat-lookalike weeds growing among the wheat). It’s easy to say you believe in Jesus here, and many mean-spirited or foul-mouthed or perverted people do say so.
For the purest Christianity, look in places where the Church is persecuted.
