This article addresses the issue of legal communication within natural law. Law has an important role, in relation to civilization and legal culture and one of the means through which law influences both culture and civilization is legal communication. The patterns of legal communication should be analyzed from the perspective of all important schools of legal thought: natural law, legal positivism, historical school of law etc. In this paper, the perception of law, through legal communication, within natural law is discussed and analyzed, from the principles and statements of Aristotle to the writings of St. Bernard of Clairvaux, St. Thomas Aquinas and later to the theories of Hugo Grotius. This study also aims to prove that the difference between legal communication within the major schools of legal thought does not regard the essence of communication or the various principles of law, but merely the perception of law, which varies from one school of thought to another.
