United by a Prayer Book
All Episcopal services whatever their style—and they vary from simple spoken ceremonies to elaborate sung ones—follow those laid out in the 1979 Book of Common Prayer. It ultimately traces its history back to the first Prayer Book of the English church, produced in 1549, following the separation from Rome. Services involve participation from the congregation and follow the same essential forms. This means that on any given Sunday an Episcopalian can walk into any Episcopal church (and with small local variations, any Anglican church in the world) and take part in a familiar worship service.
