I will make a confession- although I have a concern for the worship life of the ELCA, I have done very little to contribute to the new worship materials that will be published this fall. It seems to me, from what I have seen thus far, that the new book will simply contain some tweaking of what is already our traditional ordo . There will also be new hymns, some new musical settings of the liturgy, etc.
I do not have a problem with these updates. On the other hand, I do not think they constitute a renewal.
What do I think a renewal of worship would look like in the ELCA? I think the main renewal I'm encouraging is for the whole people of God to contribute to the worship life of our congregation, and not just a few people assigned roles like assisting minister, lector, or pastor.
We have already begun, in our church, to invite testimonials from parishioners on a variety of subjects. Also, each week we have "faith conversations," time for people to break out into small groups to discuss an issue of faith with each other.
I think something like this, and even more of it, would be an actual renewal movement in our worship. Tweaking the existing liturgy just won't cut it- it's far too passive.
Also, to invite this kind of participation on the part of the laity would do two things. First of all, it would shift the renewal away from "style"- contemporary, international, traditional, ancient-future musical settings- and towards an actual renewal of the congregation, where parishioners learn in worship how to share their faith, so that there is an actual practice in worship that rehearsal for the sharing of faith in the world.
Second, it would take seriously the admonitions Paul makes in his letters that there are a variety of gifts, and that people are called to speak in worship, to prophecy, and this is not just the work of an individual ordained pastor.
So, my plan, because I am convicted, is to shorten my sermons (which now average around 25 minutes) so that there can consistently be time for the whole congregation to share the gifts they have received in the Spirit. In this matter, we could learn from the Quakers, although I do not agree with the Quakers that silence is to be a primary mark of Christian worship. Maybe I have mis-interpreted their practice. But I do know that they make space for people to speak a word of the Lord.
