A difficult expergefaction??

I just turned my word of the day calender and today the word is "expergefaction". I love it. I'm going to try and incorporate it into my daily speech if possible. I have to wrap my head around the correct way to use it, but it is a lovely one. I still love words. I was discussing this fact with a group of people on Sunday evening last, and i remarked that in our reformed circles, we ought to have a fairly good grasp of the English language (or at least how it was, oh, i don't know, 200 years ago? I'm just guessing here and i'm sure i'm wildly out). What with words like ebenezer, effulgence, wilt, chastens, unfettered, pavilioned, hence, wert, canticle, deigned, henceforth, wretch, vexed, languor, paraclete, unction, schisms (that's always been a favorite of mine, not for the meaning of course but rather for the interesting spelling), "peculiar honors", assauage, worldling (i loved this one too!)? Aren't they lovely? I think i'm turning into more of a word-lover each day, i know that has a really fancy term, but do you think i can think of it right now? Rather ironic, don't you think?
But the other thing that comes to my mind is what about the person who just walks in off the street or just hears this one song with archaic words in it? Are they likely to invest the time to figure out what the words mean if we don't even know sometimes and we've sung the song myriad times or will they just gloss it over and miss the richness of what is being said? Would there then be cause for updating the songs? I know for myself i would miss the words, but for the sake of those who don't know yet? Or maybe we should just be better at explaining things to our neighbours who come to church. That's probably the better option...
