I read an article on the Internet by Winston Skinner of the Times Herald in Newnan, GA., titled "St. John's Episcopal Church has plaque recalling Jefferson Davis". The plaque, of course, is because the Davis family worshiped there during the time Montgomery was the capital of the Confederate States of America and the church is commemorating the memory of this great man.
The home rented for the Davis family was only a few blocks away from St. John's. Skinner points out that the Davis family were Baptists, the Howells - Mrs. Davis's family - Episcopalians. Jefferson Davis was not a member of any church until they moved to Richmond and he was confirmed in St. Paul's Episcopal Church.
Mattie Pegues Wood wrote in "The Life of St John's Parish" that the President "bowed his head a little lower" when prayers were offered for him in his official role at St. John's. Throughout its history, St. John's has offered a place of solace and peace, and I am sure that was of great benefit to President Davis.
