I'm looking for texts used in church orders of service, so feel free to add variations.
Grace Reformed Church, UCC, Washington has printed in its worship bulletin a familiar injunction: "Kindly maintain a reverent silence prior to Worship Service. Thank you." Some Unitarian Universalist churches make a oblique request by quoting Emerson, how he loved the quiet in church. I've been to others that say in so many words "We talk to God in worship and with each other afterwards."
Have you seen other formulations? Does anyone have the Emerson quotation and its source?
