We're now in the middle of some of our discussions on worship. We have a Psalter Revision Committee working to publish a new psalter, hopefully by 2008-ish. In my humble opinion, they're doing really good work. You can imagine how many opinions are being expressed. They're doing a good job taking the rough, stilted, King James-ish language out and putting more accurate, singable translations in. I also really like some of the new tunes. But when it comes, it'll be a big adjustment, regardless of how sympathetic a congregation might be to the new psalter.
We also have a committee to revise the directory for public worship. There's nothing to vote on this year, but I imagine their update report will generate some debate as well. Their initial work relies on the idea that worship is covenant renewal; this is based on synod's adopted position paper on worship, which you can find here.
