The following published in the December 1962 issue of Ebony -- you may or may not be able to see the page images -- is a sermon by Unitarian Universalist minister Eugene Sparrow, then director of field services for the Midwest Unitarian Universalist Conference. Needless to say these were early days for a black Unitarian Universalist minister in so public a position, and for the UUA -- then barely a year old -- itself. Despite the title, it seems a better-than-average and pleasingly personal example of period "biblical humanist" thought.
