He died in March 1971 and was succeeded by Bishop Michael George Bowen, who was translated in April 1977 to head the Archdiocese of Southwark.

The diocese itself covers the administrative counties of West and East Sussex, Surrey outside of the Greater London Boroughs, and the unitary authority of Brighton & Hove.

Situated in the South East of England, the diocese encompasses many villages and smaller towns, as well as highly populated parts of Surrey, central Sussex and the coastal region running from Chichester to the Kent border.

The first pilgrimage took place in 1975 around the diocese but has since gone on to include cross-country routes through England and Wales, with different themes and stops at various churches and cathedrals.

In the early 2000s, the sexual abuse scandal in Arundel and Brighton diocese hurt the public's trust in the work of local diocesan officials.
