Abstract

The fundamental tenet of Chondogyo is human beings are Heaven (innaecheon, 人乃天. This means nothing less than that man is God. This principle was boldly set forward by Revered Teacher Euiam, the third head of Chondogyo, and remains a cardinal tenet of the Church to the present day. Although this tenet was formalized under Revered Teacher Euiam, it has its origins in the Great Master’s affirmation I serve God within me (sicheonju, 侍天主); words which give expression to that which is at the very heart of Chongdogyo religious thought.
