A lectionary () is a book or listing that contains a collection of scripture readings appointed for Christian or Jewish worship on a given day or occasion. There are sub-types such as a "gospel lectionary" or evangeliary, and an epistolary with the readings from the New Testament Epistles. History By the Medieval era the Jewish community had a standardized schedule of scripture readings from both the Torah and the prophets to be read in the synagogue. A sequential selection was read from the Torah, followed by the "haftarah" – a selection from the prophetic books or historical narratives (e.g. "Judges," "Kings," etc.) closely linked to the selection from the Torah. Jesus may have read a providentially "random" reading when he read from Isaiah 61:1-2, as recorded in , when he inaugurated his public ministry. The early Christians adopted the Jewish custom of reading extracts from the Old Testament on the Sabbath. They soon added extracts from the writings of the Apostles and Evangelists. Both Hebrew and Christian lectionaries developed over the centuries. Typically, a lectionary will go through the scriptures in a logical pattern, and also include selections which were chosen by the religious community for their appropriateness to particular occasions. The one-year Jewish lectionary reads the entirety of the Torah within the space of a year and may have begun in the Babylonian Jewish community; the three-year Jewish lectionary seems to trace its origin to the Jewish community in and around the Holy Land. Within Christianity, the use of pre-assigned, scheduled readings from the scriptures can be traced back to the early church, and seems to have developed out of the practices of the second temple period. The earliest documentary record of a special book of readings is a reference by Gennadius of Massilia to a work produced by Musaeus of Marseilles at the request of Bishop Venerius of Marseilles, who died in 452, though there are 3rd-century references to liturgical readers as a special role in the clergy. Western lectionaries In the Latin liturgical rites before the Second Vatican Council Before the liturgical reforms of Vatican II, the Latin liturgical rite used a one-year lectionary consisting of a limited selection of sacred readings from the Scriptures. The reason to these limited selections is to maintain consistency, as is a true feature in the Roman Rite. There is one reading to be proclaimed before the Gospel, either taken from
