For a small church we currently have a relatively large Sunday School:
We provide childcare for the young children during the service. During the regular worship, there is a children's sermon, after which there is a Sunday School for the older children until the end of the service. A small group takes turns teaching and organizing, usually for several months at a time to provide continuity. With some regularity, other members of the congregation attend the children's Sunday School to talk about their own work or ideas.
The Youth Group meets on the third Saturday of every month. Click here for details.
