Eureka Classis
On June 7, 1911, seven ministers and sixteen congregations organized to form the Eureka Classis. The name of the Classis came from the Greek word ‘eureka’ which means ‘I found it’ and not on the town Eureka, South Dakota, where the second meeting of the Classis would be held. The name was designed to mean that they had found a solution to their doctrinal problems with the rest of the denomination.
Aranyaka
Several theories have been proposed on the origin of the word "Aranyaka". Originally, as per Oldenberg (1915), it meant (dangerous texts to be studied in the wilderness (Taitt. Ar. II). A later, post-Vedic theory holds that these texts were meant to be studied in a forest, while the other holds that the name came from these being the manuals of allegorical interpretation of sacrifices, for those in Vanaprastha (retired, forest-dwelling) stage of their life, however the Vanaprastha Ashrama came into existence only well after that of the Sanyasin (Sprockhoff 1976) -- according to the historic age-based Ashrama system of human life.
