That’s a frequent critique of our UU worship and spirituality. It’s always personally legitimate for the speaker even as they identify with our religious orientation. How might I hear it as well?
Both Unitarian and Universalism evolved from Christian tradition, with Jesus as exemplar and model, now one among many. As he is one of our exemplars, i.e. one “form through which the distortions of humanity are laid bare” (Richard R. Niebuhr), could he and his teachings not be more a part of our religious understanding and practice? What might that mean?
