The Communion Service includes three readings from the Bible: a chapter from one of the Gospels, from one of the Epistles or another part of the New Testament and, since 1992, from the Old Testament. Texts are picked from an official list following the church year. Some liturgical features have a fixed content but are free to the form. This accounts for the Common Prayer following the sermon, where the priest is encouraged to mention the royal house. Some will simply mention "the Queen and all her House" whereas others will list all members of the royal house by name and title.
