A lectionary is a table of readings from Scripture appointed to be read at services on different days. It provides a common path and experience for all congregations to grow in faith and understanding of Scripture.

The Revised Common Lectionary, published in 1992 and officially adopted by The Episcopal Church in 2006, takes into account constructive criticism of the Common Lectionary based on the evaluation of its trial use, and as the current prayer-book lectionary, is a three-year cycle of Sunday Eucharistic readings. Over the three years, the majority of Holy Scripture is covered.
