We do 2 different services. The early service is "all hymns, all the time" and is very traditional in terms of music. It draws more people who grew up in church and like the hymns.
The later service is not a contemporary service in terms of harder music or, for lack of a better word, rock. We may sing a hymn but it's in the context of more recently written with a more contemporary style. It draws people who are first timers in church or have been gone a long time. This cuts across age demographics. Older people who are new believers like this service because it is much more basic.
What is there about this generation that won't tolerate what we had for two hundred years without significant change?
Why just go back 200 years? Why don't we go back to the music of the early church? If it was good enough for Paul, why isn't it good enough for us.
200 years ago, Christianity was a base line for most people. They may not have believed but they accepted the Bible and had some understanding of Christ and His message. Today, many of the people in our small community have no basic understanding of Biblical Christianity. They don't know how to sing a hymn or how the verses are sung and then the chorus. Even the believers grew up with a different style of music, then we ask them to step into a time machine and go back in time. Our contemporary service doesn't ask them to go back to the future.
By the way, the sermons in both are the same, but I have to spend more time defining terms in the 2nd service because they don't kow biblical terms.
