Not long after the
General Convention readmitted the Confederate bishops after the
American Civil War, the clergy and laity of Virginia and West Virginia met in May 1867, and selected Whittle as Bishop
John Johns' assistant. He was consecrated on April 30, 1868. Recovery from the devastation of the war preoccupied Bishop Whittle's episcopate, both as Bishop Johns' assistant and as his successor beginning April 4, 1876. With the help of his wife Emily, Whittle established various charitable institutions in Richmond. In 1875, he established the Protestant Church Home, and remained on its board of directors until his death in 1902 (Emily Whittle was the Home's first President, serving for at least 10 years from 1877) Emily Whittle also established the first Richmond chapter of the
Young Women's Christian Association. The Diocese of Virginia split twice during Whittle's episcopate. The Diocese of West Virginia was created in 1877 to correspond to the new state created during the Civil War. The Diocese of Southern Virginia was created in 1892, with the understanding that a further division would soon occur (and the Diocese of Southwest Virginia was created after bishop Whittle's death). In 1897,
Robert Atkinson Gibson was elected as bishop Whittle's Coadjutor with right of succession (the previous assistants having moved to the Diocese of Southern Virginia or died) and soon consecrated. Although Bishop Whittle was known for his personal rectitude and lack of ostentation, by the end of his episcopate,
Jim Crow laws had restricted the participation of African-American Episcopalians within the diocese, and African-American Virginians within the Commonwealth. While Bishop Whittle in 1878 had established the
Bishop Payne Divinity School in
Petersburg, Virginia to prepare African-Americans for ordination (which ultimately merged with VTS) and ordained
George Freeman Bragg as deacon in 1887 and as priest the following year, in 1899 the diocesan council approved restricting Bragg's voice (and that of other non-white clergy) to the Convocation of the Missionary Jurisdiction. Bishop Whittle also was active in sending missionaries to Brazil, and one of his last acts was signing a petition of clergymen opposing the war in the Philippines. However, he died disappointed that he had failed to stem the
Oxford Movement within the Anglican Communion and within his diocese. ==Death and legacy==
