The Gospel Book, Evangelion, or Book of the Gospels (Greek: Εὐαγγέλιον, Evangélion) is a codex or bound volume containing one or more of the four Gospels of the Christian New Testament – normally all four – centering on the life of Jesus of Nazareth and the roots of the Christian faith. The term is also used of the liturgical book, also called the Evangeliary, from which are read the portions of the Gospels used in the Mass and other services, arranged according to the order of the liturgical calendar.[1]
