Scientists say everything changes constantly. We may say, nothing is constant, only change. Yet, many individuals and communities assume that old patterns of existence will work forever. But time and the realities of life challenge us all, and call us to revise our principles, creeds, laws, our ways of being and thinking. From the circles of the ancient scientist Archimedes, to the circles of love in which Jesus tried to create the kingdom of God, to the round table of King Arthur who believed in the power of equality and mutual respect, we see examples of people who have expanded their circles to include others. What kind of changes and challenges do we experience in Transylvanian Unitarian and in American Unitarian Universalist circles?
