One Sunday morning in 1865, a black man entered a fashionable church in Richmond, Virginia. When Communion was served, he walked down the aisle and knelt at the altar. A rustle of resentment swept the congregation. How dare he! After all, believers in that church used the common cup.
Suddenly a distinguished layman stood up, stepped forward to the altar, and knelt beside the black man. With Robert E. Lee setting the example, the rest of the congregation soon followed his lead.
