Lectionary includes readings from the Revised Common Lectionary for years A, B, and C. The RCL is very common with most mainstream churches, including Episcopal, Lutheran, Methodist, and Presbyterian, among others. If you are part of these denominations, chances are Lectionary will match readings from your church services on most days, or contain only a slight variation from what your church is using.
You can compare your church bulletin against the readings you would have seen this past Sunday in Lectionary using the Revised Common Lectionary (Book of Common Prayer - 2007) calendar:
Readings for Sunday, November 24, 2013:
- Jeremiah 23:1-6
- Canticle 4 or Canticle 16 or Psalm 46
- Colossians 1:11-20
- Luke 23:33-43
For those not using the RCL, Lectionary also includes readings from the original Book of Common Prayer in it's 1979 form. It also includes variations of the RCL specific to various churches, such as the Episcopal Church of the United States. If you are interested in Lectionary but find it doesn't match the liturgical readings of your church, just drop me a line - I might be able to add a calendar that fits your needs.
