This is a non-denominational independent nonprofit association dedicated to Scripture research, founded in 1909 in Los Angeles, California. A E Knoch, deceased, was the founder of this association. He is known as the translator of the Concordant Literal New Testament with Keyword Concordance, and the Concordant Version of the Old Testament.
This association was my second mentor that guided me further in my spiritual journey, since mid 1970s.
