This liturgical object, central to Catholic worship, contains selections from the four canonical Gospels: Matthew, Mark, Luke, and John. These pericopes, or passages, are specifically chosen for proclamation during the Mass throughout the liturgical year. It is distinct from a complete Bible or even a New Testament, focusing solely on the Gospel readings used in the liturgy.
Its significance lies in its role in highlighting the words and actions of Jesus Christ during the celebration of the Eucharist. It is often richly decorated and treated with reverence, reflecting the importance the Church places on the Gospel message. Historically, illuminated manuscripts of this nature represented a significant artistic endeavor, showcasing the skills of scribes and artists in preserving and embellishing sacred texts. Its presence underscores the centrality of the Gospels in Catholic faith and practice.
