We are always into the habit of simplifying. We tend to think that people in the pew will always have a hard time understanding theological terms. They sound technical and so we are afraid to even mention them. One need not be afraid, what you do is communicate and help the would-be disciple understand the terms. Just have a little faith that people in the pew are not dumb you have to dumb things down.
So I happen to meet one of the young adult member of my ex-church. I have been away for more than a decade and by this time he is now in his early 30s having spent roughly all of his life active in church. So I asked him, if he ever heard of the thing called "justification". He gave a guess and it was off. What about the "Apostle's Creed"? Heard of it but do not know what it is and what it means or should he have to know it.
So then I spoke to some folk who have been in Augustana most of their lives and I mentioned the "solas" of the Lutheran Reformation, like sola scriptura. "Yes, yes, yes, but ... that was a part of our heritage". Meaning? It is not relevant today? That was way back then but that was it. I somewhat half protested - Huh? It is not something you put on the shelve but something you live by, it is a principle, and principles are always used, even today.
We can cut some slack for the young man I met, he is not in Wittenberg. He does not have the privilege of catechesis. However, I am bothered by the attitude of folk from the Reformation who think the solas are just one nice stuff of history.
I am wondering if these attitudes are part of the dumbing down process, a result of being intimidated by the pressure of being relevant, so much so, that we do not see the need to discuss technical and theological terms/ideas, even historical ones. May be that is also the result of no longer being in "reformation"? That is at least my suspicion.
