Thanks for posting this excellent article, OP.
There are currently 73 names on the GRPL and many threads are still posted to and by them. The list is found on Nobdysfool's homepage.
What a beautiful explanation of the purpose of the liturgy! Thank you for the post. I think that liturgical congregations should teach the purpose of the liturgy along with the teaching of the catechism, so that members can appreciate what they are doing in worship and why.
I do not understand why congregations would choose to not have communion every Sunday in a Reformed church. Sundays are a celebration, why would supping together not be included?
