Since I suspect that many people will be heading home before 4 PM on Sunday, the time of the closing worship service. There is a plenary at worship time on Sunday, so quite a few people will seek other worship options Sunday morning. Worship at First Unitarian in downtown Portland should be full.
I think that it is important that we have significant worship at GA, and by significant, I mean worship in which the elected leaders of the association play substantive liturgical roles. I appreciate the fact that the preaching duties are spread around and that we get to hear from a variety of ministers from the GA pulpits. But I also want to hear sermons from the President of the UUMA, and sermons from the President of the Association. I think that that religious leadership often comes down to the ability to inspire or to cast a vision. The corporate worship service and the sermon are forms of speech designed to call forth expressions of visionary leadership.
Part of the community forming power of worship is that it forms and designates community leaders who gain authority by their sustained and repeated inspiration of others. The GA practice of rotating the most important preaching duties around to different ministers is like the lay-led fellowship which rotates the worship leadership around a group of competent speakers, none of which have the role of vision-caster for the group.
