You know, I don't think I like the term "Layman" or "lay" or "laity" any more. Why? Well, it used to just mean... the people. The folks. You had the pastor there was was to preach to the people - the laity. Just meant all those folks who didn't do the preaching or sacramental stuff - nothing more, nothing less.
Now the term "layman" almost has a... second tier status... not necessarily in the Church, but outside of the Church. It has the sense of "non-professional"... almost meaning "amateur" or "hobbyist". Are you a carpenter? Nah, I just do it on the side... I'm a lay carpenter.
I'm not trying to say that this is common usage (how many places use the word "lay" anyway) - but that this is sort of the connotation that the word has derived.
Indifferent. Amateur. Not really dedicated. Not "real".
And these connotations have nothing, nothing to do with how the non-clergy are to be viewed in the Church. Yet what happens? Well - what is your normal reaction when you feel marginalized by your title? You try to "move up the ladder" some how.
Being a pastor is not belonging to a "class" of Christian -- it's not like a Pastor is a major league Christian and the laity are just AAA... and maybe someday they might make it to the show.
You know what a Pastor is. A Pastor is just one of the congregation, the people, who has a specific calling, a specific vocation.
You know. A specific job.
I mean... is one a better Christian if one is a farmer, or a doctor, or a machinist? Then why in the world would we think being a pastor would make one a better or higher or more important Christian?
Maybe in part its because there is baggage with that term laity... baggage that has no business being there.
I really liked Prof. Weinrich's "BP" model -- the Church consists of Bishop and People. Nothing wrong with being people... and being the Bishop's just an office, nothing more, nothing less.
