I am working on seeing how a 21st century, mainline, traditional congregation can receive new life by looking at the words of the ancient church. I keep seeing, and hearing about, people who have left the mainline church for the big megachurches but who then come back because they want more tradition, more liturgy in worship. One of the things I keep coming back to is developing a sense of authenticity in worship. Like many of you I have heard about the importance of authenticity for postmoderns, as well as for others. Folks in the pews (and in the pulpit) want to know what is ‘real,’ they want to know that what we are doing and who we are is genuine. But that can be a slippery concept. How do you define authentic worship? What determines it? What does/can it look like?
