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.
Hallaca
According to Adolfo Ernst, the word "hallaca" evolved from the indigenous Guarani language, stemming from the verb "ayua" or "ayuar", meaning "to mix or blend". From there, the construction "ayuaca" (mixed things) devolved to "ayaca" and ultimately to "hayaca" or "hallaca" (using Spanish silent "h" when written). Another version presumes that the word comes from an aboriginal language of the West of the country, whose meaning is "wrapping" or "bojote".The earliest use of the word in the modern sense is in a 1781 document of Italian missionary linguist Filippo Salvatore Gilii.
