I went to a well constructed family service today. Points which stand out are:
(1) Involving the whole congregation in acting out the gospel story: once Jesus, Bartimaeus, and Twelve Disciples were selected out, the rest of the congregation became the crowd.
(2) The 'message' came through the mix of reading and acting and modest additional comment.
(3) The intercessions also involved the whole congregation - divided into groups per major topic, and requested to come up with items for prayer. No one was asked to pray - the intercessor did the praying - so no embarrassing pressure on people.
