He died on 9 September 1890 at the height of his reputation, having nearly completed a biography of Pusey, whom he admired; this work was completed after his death by John Octavius Johnston and Robert Wilson. Liddon's influence during his life was due to his personal fascination and his pulpit oratory rather than to his intellect. As a theologian his outlook was old-fashioned; to the last he maintained the narrow standpoint of Pusey and Keble, in defiance of modern thought and modern scholarship. The publication in 1889 of "Lux Mundi" edited by Charles Gore, a series of essays attempting to harmonise Anglican Catholic doctrine with modern thought, showed that even at Pusey House, established as the citadel of Puseyism at Oxford, the principles of Pusey were being departed from. He was the last of the classical pulpit orators of the English Church, the last great popular exponent of the traditional Anglican orthodoxy, with the exception of John Charles Ryle (1816-1900), the first Anglican bishop of Liverpool (1880-1900).
