Unitarians and Universalists
While the name of the organization is the Canadian Unitarian Council, the CUC includes congregations with Unitarian, Universalist, Unitarian Universalist and Universalist Unitarian in their names. Changing the name of the CUC has occasionally been debated, but there have been no successful motions. To recognize the diversity, the abbreviation is often written as U*U (and playfully read as "You star, you"). Note, not all CUC members like this playful reading and so when these people write the abbreviation they leave out the star(*), just writing UU instead.
