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.
Erecura

Many different Latinised forms of this goddess’s name occur: "Aeraecura" at Perugia; "Aerecura" at Mainz, Xanten, Aquileia and Roşia Montană; "Aericura" at , "Eracura" in , "Ercura" at , "Erecura" at , Tongeren and Belley in Aube; "Heracura" at Stockstadt am Rhein, "Herecura" at , Freinsheim and Rottenburg am Neckar, where the form "Herequra" is also found.
