If you are looking for ways to develop multigenerational worship services then look no further than the UUA’s WorshipWeb. Engaging a wide spectrum of ages in one service can be challenging, but WorshipWeb offers lots of resources to help make it happen.
WorshipWeb has drawn together articles on multigenerational worship from the Alban Institute and other sources. One useful article is the staff group of the MidAmerica Region’s “Ten Good Ideas About Multi-Generational Worship,” which include “keep it simple,” “keep it moving,” “think homily rather than sermon,” and “use multiple learning styles, engaging all five senses.”
WorshipWeb also includes a compilation of InterConnections articles about multigenerational worship and has a list of anthologies of stories and sermons for children. There are also book suggestions, such as Come Into the Circle: Worshipping with Children by Michelle Richards, and Story, Song, and Spirit: Fun and Creative Worship Services for all Ages by the Rev. Erika Hewitt.
