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.
Europa (consort of Zeus)
It is common in ancient Greek mythology and geography to identify lands or rivers with female figures. Thus, "Europa" is first used in a geographic context in the Homeric Hymn to Delian Apollo, in reference to the western shore of the Aegean Sea.
As a name for a part of the known world, it is first used in the 6th century BC by Anaximander and Hecataeus.
The weakness of an etymology with εὐρύς ("eurus"), is 1. that the -u stem of εὐρύς disappears in Εὐρώπη Europa and 2. the expected form εὐρυώπη euryopa that retains the -u stem in fact exists.
