For Sunday worship, the Episcopal lectionary provides a weekly three-year cycle of Scripture readings.
The association of particular texts with specific days began in the fourth century. There are two lectionaries in common use in the Episcopal Church: the Revised Common Lectionary (RCL) and the Book of Common Prayer Lectionary (BCP). As with most Episcopal churches, the Church of the Redeemer has switched to the RCL for its weekly Sunday lectionary.
The RCL version provides semi-continuous passages from the Old Testament week to week, as well as thematic connections between the readings from the Old Testament, New Testament, and Gospel every week.
For the readings in most of its services, the Redeemer uses the New Revised Standard Version (NRSV) of the Bible.
