The beliefs of Episcopalians are quite diverse. The official standard is the Book of Common Prayer, but some parts of that are more clearly doctrinal than others. In addition, interpretations of doctrine vary widely from individual member to individual member.
Some people interpret the doctrines literally.
Others interpret them symbolically. Many find the doctrines to be leaping off points which aid them in their prayers and meditations. The ecumenical creeds, both Nicene and Apostles' , are used by the Episcopal Church in its worship day by day and week by week. They are ancient and universal statements of Christian faith. In addition, the Episcopal Church follows ancient tradition and includes the Athanasian Creed among its statements of faith.
