Amor Dei: A Vision of God is the second of the four Inventions for Radio.
A second invention for radio by Barry Bermange, in collaboration with the B.B.C.'s Radiophonic Workshop, with talk recorded in co-operation with the Old People's Welfare Council, Hornsey. Producer: David Thomson. An attempt to describe God in human terms, and to create, in the manner of a religious painting, an overall impression of man's love for Him. The voices were recorded from life and arranged by the author in a setting of radiophonic sound. Plainsong Antiphon John Hahessy (boy soprano) - unacc. 16-Nov-1964. 
When I was doing the Inventions with Barry Bermange he wanted sounds which would sound like a Gothic altarpiece. 'Oh,' I said, 'yes. What a good idea. But what do you really mean? What sort of sounds?' He said 'Well, give me a pencil and paper'. I did, and with great care and elaboration he drew me a beautiful Gothic altarpiece and said 'That's the sort of sound I want'. 
Barry Bermange said that he himself thought of Amor Dei as ‘rather in the manner of a Renaissance painting with the believers in God in the foreground or centre and half-hidden disbelievers looking out from shadowy places round the edge of the painting.’ He has made this programme in four sections. In the first you will hear several thoughtful voices groping towards God, feeling their way into something undefined. In the second, some more assured voices cite concrete images; a defined notion of God begins to emerge. The third is a contest between those who love God and those who cannot believe in Him. The assured and confident voices in the last section are inspired by absolute faith. 
and Jonathan Haevey's daughter says that
“a piece of Jonathan's called "Symphony" (1966) was partly inspired by Delia's "Amor Dei", and "Symphony" [went] on to inform some of his later work. [...] Jonathan [said] he liked the breathing quality of the repeated chords.”
There is an extensive analysis of the piece's musical structure and the circumstances surrounding its creation in Special Sound, pp.102-111.
The work is in four movements, each of which has its own page:
1. Groping towards God (7:59)
"Several thoughtful voices groping towards God, feeling their way into something undefined"
2. Rorate Coeli (9:02)
3. "I'd like to believe in God, but..." (14:35)
"A contest between those who love God and those who cannot believe in Him"
4. "There IS a God!" (14:27)
"The assured and confident voices in the last section are inspired by absolute faith."
Delia prepared an abridged "transcription" version of the suite for transmission outside the U.K.
