The Gospel in Christian liturgy refers to a reading from the Gospels used during various religious services, including Mass or Divine Liturgy (Eucharist). In many Christian churches, all present stand when a passage from one of the Gospels is read publicly, and sit when a passage from a different part of the Bible is read. The reading of the Gospels, often contained in a liturgical edition containing only the four Gospels (see lectionary), is traditionally done by a minister, priest or deacon, and in many traditions the Gospel Book is brought into the midst of the congregation to be read.
