Being from the dumbed down baby food version of the church I often find the vocabulary on PB foreign to my ears and eyes. I feel like Jethro Bodine at a MENSA convention. I have often thought of suggesting a section for newbies where people would post basic definitions and explanations for people new to reformed thought. I opted not to because I want others to have to work for it like I am.
Anyway, there is a good discussion on big words in the Bible this week on http://www.whitehorseinn.org/
I like that they not only discuss what the words really mean but they discuss the facts that often speakers ASSUME that everyone knows what they mean when they use a word that is uncommon to the uninitiated. Some of us just don't know the lingo yet but boy could I do some charismatic/megachurch speak that would send you reaching for your decoder.
