Archbishop of Canterbury, 1883–1896
In 1883 he was appointed Archbishop of Canterbury.
Five years later Benson avoided Edward King, Bishop of Lincoln, being prosecuted before a lay tribunal under the Public Worship Regulation Act 1874 for six ritual offences by hearing the case in his own archiepiscopal court (inactive since 1699). In his judgement (often called "the Lincoln Judgement"), he found against the bishop on two points, with a proviso as to a third that when performing the manual acts during the prayer of consecration in the Holy Communion service, the priest must stand in a way that is visible to the people.
Benson tried to amalgamate the two Convocations and the new houses of laity into a single assembly. In 1896 it was established that they could 'unofficially' meet together.
In September of the same year, the papal bull Apostolicae curae, which denied the validity of Anglican orders, was published and Benson had started a reply. He preached his last sermon at St Patrick's Cathedral, Armagh on 27 September: there is a memorial to him in the north aisle there. He was taken ill while attending Sunday service in St Deiniol's Church, Hawarden, Wales, on 11 October 1896, during a visit to the former Prime Minister, William Ewart Gladstone. His death was attributed to heart failure. Three days later his body was put on the train at Sandycroft station to be returned to London.
He was buried at Canterbury Cathedral, in a magnificent tomb located at the western end of the nave. The tomb is emblazoned with the epitaph Benson had chosen: Miserere mei Deus Per crucem et passionem tuam libera me Christe ("Have mercy on me O Christ our God, Through Thy Cross and Passion, deliver thou me").
His work concerning Saint Cyprian, Cyprian: his life, his times, his work, was published posthumously, in the year after his death.
