Human language is a necessary tool of communication not only for everyday life, but also for the most serious and most important areas of life like the sciences, medicine, religion, psychology, sociology, etc.  Every professional discipline has its own jargon that often sounds like a foreign language to outsiders.  Learning a particular jargon is basic to the profession.  Insider language is an aid to communication within a professional group, but communication with outsiders becomes a necessary task that often requires more verbiage and effort than speaking with a professional peer.

The word theology is a religious jargon combining two Greek words theos, God, and logos, word or study – a word or study of God.  Theologian John Macquarrie simplified the meaning of theology to “God-talk.”  He wrote that theology has its own rules of logic distinct from chemistry or history.  The rules of theological language do not allow a description of deity under the same rules of a material object or even a human person.
