According to WordCount, [2009. http://www.fabrica.it/wordcount seems to be gone] the word universalist is the 64487th most frequently used word in English, between the marginally more common bukhara, rolston, and standardizing, and the marginally less common emm, routh, and smasher. I hope and assume there are a couple of proper nouns (certainly Bukhara) in that list or I really need a vocab refresher.
The word universalism, which is more commonly used in fields other than theology comes #48886 between petrology and lucan.
Who knew?
I believe bukhara is a kind of carpet, originally from Bukhara, of course.
