Watch and Pray (Derek Parker) has followed up on the small congregation (conventional church, house church, worship group, the latter perhaps associated with the UUCF) worship book idea I mentioned earlier.
To his list of four liturgies, I would add a service of welcoming new members (to be used within another service) and a brief service upon hearing of a death, perhaps one flexible enough to be used in times of disaster.
The doxologies he mentions would be nice I assume he means GENEVAN PSALTER 100, but perhaps not and tunes could vary based on the ethnic and social background of the congregation.
Ditto the "easy to sing hymns" which will be the key. I think forty hymns, and another forty psalms and canticles (better and more properly described as "songs from the Bible") would really help.
Now, from whence the content?
A starting place.
