Christianity is meaningful because of its impact on historical existence as such. It reveals the purpose of human existence at a crucial stage of humanity's cultural evolution. Theology has the import function of presenting Christian belief in a credible and intelligible form to the broader society.
Many churches today are failing this important issue. It's not a crisis. It is the crisis in today's secular world. Church is a money-making scheme, the bigger the better. I have visited one such church four times now and enjoyed the "show" they put on, better than any Lawrence Welk or Billy Graham program wrapped into one. The old preacher, Sager, got too emotional with his screeching, arguing, yelling and his actor's hand gestures as he used Paul as a source for "bad behavior." I haven't seen such a show (usually it is fun to watch, but not this time) since I was a young girl here and 'visited' a Church of God Holiness congregation just two doors down from where I lived. Those folks scared me. Sager did not scare me, he made me mad! I told him after his first sermon that he 'hit below the belt' so to speak with his condemnation of the Methodists. Less than a month ago, he told me 'they' love the Methodists there. I had already been told otherwise, that we are too liberal. This time he showed his hypocrisy and bigotry. There were no blacks in this church of rich people. Always before, it has been a grand performance of the highest caliber, but his repetitive put-downs of other denominations was going too far. I don't know whether he toned down the second sermon, but I doubt it -- as he had already told me to go back to the Methodists! That was quite a shock, as I had been considering going back to my roots of the Baptist profession. I profess now that I will not be a 'slave' to anyone or any deity. This man worships money and the fine homes and trips he has as the perks of being senior pastor. He is a false prophet.
Of the twelve crises Marshall Johnson expounds upon, I think the most important is 'The Crisis of Competing Truth-Claims.' The aforementioned preacher who walked around (did not stay even close to the pulpit, but that was just for show) pretending to involve the audience (you couldn't call it a congregation) is a charlatan of the worst order. The problem is that there are many such 'Billy Sundays' out there disrupting the American people to be 'slaves' to them and their bigoted opinions.
