Both 8:00 and 10:30 services are Holy Communion services that take place in the Sanctuary. Both have a full-length sermon. What's the difference?
8:00 - Spoken, Traditional (Rite I) Worship
This is a Holy Communion service in Elizabethan-era language ("thees and thous") and follows the Book of Common Prayer rubric directly. There is no music, and it finishes in just under an hour. Read the service here.
10:30 - Choral Holy Communion
This is a Holy Communion featuring the choir from September through Pentecost (May/June). The service is in contemporary language. We use material from the 1979 Book of Common Prayer, but also include other material approved for use in worship, on a rotating basis by season of the Church Year. Some of the resources we draw on are: The New Zealand Prayer Book, Enriching Our Worship, and liturgies of the Iona Community.
From the Sunday after Pentecost through Labor Day, there are Celtic Summer Services, described in this column. Celtic services are drawn primarily from Iona Community materials.
