Worship Resources is a great resource for your worship planning needs from Advent 2020 to Advent 2021.
A new feature of the book is the use of the Old Testament scriptures for over half of the service outlines. The theme and worship planning for those Sundays will use the Old Testament scriptures recommended in the Revised Common Lectionary (RCL) for Year B (semi-continuous reading).
Weekly worship outlines include Community of Christ worship themes, lectionary-based scriptures, ways to engage all ages, recommended hymns from Community of Christ Sings, drama scripts and responsive readings, special prayers, focus moments, worship settings, and more.
Also helpful are the two Sermon and Class Helps that provide commentary on the Lectionary scriptures each week. They are also good resources for personal or small group study.
