David Lodge, who died on 1 January at the age of 89, was a writer and academic who used to describe himself, echoing Graham Greene, as an “agnostic Catholic”. His fiction was infused with themes of the faith of his youth – set against a backdrop of the theological controversies that marked the 1960s as the Church attempted to bolster her teachings in the face of the sexual revolution that had swept across western societies on both sides of the Atlantic in the decades following the Second World War.
