Many congregations accepted their first black members. Some slave owners were predictably upset. The Weekly History contained an account of a Boston slave owner who walked in on his slave preaching to himself, imitating Whitfield's dramatic style. The owner, no fan of revival, was so amused that he called together his friends for some after-dinner entertainment.Oh, that we would be surprised once again by the Holy Spirit
'Supplying his friends with pipes and glasses all around, he instructed his slave to mount a stool in the center of the room and preach as he had the day before,' historian Frank Lambert explains.
