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.
Sloboda Ukraine
The name derives from the term "sloboda" for a colonial settlement free of tax obligations, and the word "ukraine" in its original sense of "borderland". The etymology of the word Ukraine is seen this way among Russian, Ukrainian and Western historians such as Orest Subtelny, Paul Magocsi, Omeljan Pritsak, Mykhailo Hrushevskyi, Ivan Ohiyenko, Petro Tolochko and others. It's supported by the Encyclopedia of Ukraine and the Etymological dictionary of the Ukrainian language. In Russia, the name "Ukraine" (Russian: "Ukraina") is perceived as a calque of "okraina", meaning a frontier ("krai"), thus "Sloboda Ukraine" is known as a "free-settled frontier". In Ukraine, the region is accepted as a free settled region, part of the whole Ukraine.
