In 1972 Dr. Errico was inspired with the vision of the seven basic biblical keys which enable anyone to unlock the many mysteries of Scripture: 1) The Aramaic language. 2) Idioms. 3) Near Eastern Mysticism . 4) Near Eastern Culture – customs and manners. 5) Near Eastern Psychology. 6) Symbolism. 7) Amplification. The 7 Keys bring clarity to obscure and difficult passages of the Bible.
