What is the Greek meaning of 'canon'?

The Greek meaning of 'canon' is derived from the word that translates to 'reed' or 'measuring rod.' In ancient contexts, a reed was used as a standard for measuring length or quantity. This metaphorical background signifies that something that is considered a 'canon' serves as a standard of measure, particularly in religious, legal, or literary contexts.

In the context of ecumenical councils and church doctrine, the term 'canon' has evolved to represent a set of rules or principles that lay down the authoritative standards for doctrine and practice in the church. This is consistent with its root meaning, as these canons establish the criteria by which religious texts, beliefs, and practices are measured and validated within the tradition.

Understanding this background helps to highlight the importance of canons in shaping the structure and norms of religious communities, ensuring that there is a common standard against which teachings and practices can be assessed.
