A book for common worship

"A Book for Common Worship is a collection of music, prayers, and responsive readings for use during services of the First Parish (Unitarian Universalist) in Cambridge. The opening hymns, prayers, and congregational responses are those used regularly in our services. The responsive readings and hymns have been selected by the [Worship] committee to supplement those in the hymnals currently in use. ... The format and pagination of the book reflect the desire of the Worship Committee to have the book grow as we discover new materials..."--Introd.
