A corrector is a misdirected edifier. One who sees insights, but has not a pulpit from which to preach them.
Me, my place is to be the local nerd. Grandma has remonstrated wih me about calling myself that, but I am in fact a nerd. And if I were not in my place, it would go unfilled or at least not filled as well.
I maintain the stuff in the sound booth at church, trouble-shoot if something goes wrong... shoot, I set the whole system up to begin with. I have multiple laptops, some of which found a place in various parts of the church. I'm the one who burns copies of a CD for the praise team to practice with, the one who knows how to "get that song off youtube," or edit a song if a part (like a wild guitar solo) doesn't fit the project they're doing... I'm the resident nerd.
Some are called to be burrs. Ever seen a horse with a burr under its saddle? There was this one guy in church who was always the loudest praiser, the most active, always the first one on his feet when the Spirit started moving. One day some of the quieter people asked the pastor if something could be done about this noisy person. The pastor only said "I've been praying about the matter." A couple days later, the active praiser himself came to talk to the pastor. "Say Reverend," he said, "You know that pew where the really quiet guys sit? Think it would be alright if I could sit with them for a few services?" The pastor said, "I've been praying you would say that."
About corrections though, some corrections should not be made because some churches have different standards, because some churches
are in different places. I like to use the bowling alley illustration. In one town the bowling alley is a seedy dive where prostitutes hang out in the parking lot and the church in that town finds it necessary to have a standard against bowling. In another town the bowling alley is a family-friendly, brightly-lit, clean establishment and the church in that town needs no such standard. One church cannot (well... SHOULD not, but sometimes they do) judge the other church as reprobates and sinners for lacking this standard, and the other church cannot... er, should not judge the first church as legalistic and uptight for having the standard.
By the way... seoulsearch, do you play dominoes? You do? YOU SINNER!!! (For the record, the previous sentence was said very much tongue-in-cheek.)
I know of a church that had to have a standard against dominoes. Sound ludicrous? In most places it would be, but in this church they had a problem - more than half the congregation was skipping church to play dominoes at a friend's house on Sunday night.
