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.
Púca
The origin of the name may have come from the Old Norse term "pook" or "puki", which refers to a "nature spirit". Usage of the term in Ireland, however, may predate the arrival of Norse settlers.
In Germanic languages, such as Frisian or English, this became "pucel", "pook" or "puck". The name of the pooka may also come from the Irish word "poc", meaning a male goat, a form the creature is often said to take.
