Lectionary - Years A, B and C 

A lectionary is a cycle of biblical readings that runs through the Church Year, beginning at the start of Advent.

The Methodist Church in Britain uses the Revised Common Lectionary, which was developed in the 1980s and is now used
throughout the world by many Christian denominations. 

The lectionary for Sundays is arranged in a three-year cycle that is planned around the four gospels in the New Testament.

Year A is the year of Matthew
Year B is the year of Mark
Year C is the year of Luke

Extracts from the Gospel of John are read each year, especially around Christmas, Lent and Easter. Additional readings from John are included in the year of Mark (Year B), whose Gospel is shorter than the others. The sequence of Gospel readings is designed to assist God’s people into a deeper understanding of Christ and a stronger faith in him. Readings are grouped around the birth, baptism, ministry, death, and resurrection of Jesus.

Each year of the lectionary cycles begins on the First Sunday of Advent.
