A lectionary (Latin: lectionarium) 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.
