One of his main focuses is the dialogue between religious traditions, an interest which led him to be Joint President of the World Congress of Faiths (WCF) between 1992 and 2001. His work also explores concepts of God and the idea of revelation. Ward has also written about his opinion of a relationship between science and religion. As an advocate of theistic evolution, he regards them as essentially compatible, a belief he has described in his book
God, Chance and Necessity, and which is in contrast to his Oxford colleague Richard Dawkins, an ethologist and vocal and prominent atheist. Ward has said that Dawkins's conclusion that there is no God or any purpose in the universe is "naive" and not based on science but on a hatred of religion. Dawkins's strong anti-religious views originate, according to Ward, from earlier encounters with "certain forms of religion which are anti-intellectual and anti-scientific...and also emotionally pressuring." He has also been highly critical of materialist philosophers of consciousness such as Daniel Dennett, as well as social scientists such as Sigmund Freud and Karl Marx, arguing that they each attempt to reduce the human person into aspects of their own discipline.Ward has described his own Christian faith as follows:
I am a born-again Christian. I can give a precise day when Christ came to me and began to transform my life with his power and love. He did not make me a saint. But he did make me a forgiven sinner, liberated and renewed, touched by divine power and given the immense gift of an intimate sense of the personal presence of God. I have no difficulty in saying that I wholeheartedly accept Jesus as my personal Lord and Saviour.
He has criticized modern day Christian fundamentalism, most notably in his 2004 book
What the Bible Really Teaches: A Challenge for Fundamentalists. He believes that fundamentalists interpret the Bible in implausible ways and pick and choose which of its passages to emphasise in order to fit pre-existing beliefs. Ward argues that the Bible must be taken
seriously, but not always
literally and he does not agree with the doctrine of Biblical inerrancy, saying that it is not found in the Bible, elaborating that
There may be discrepancies and errors in the sacred writings, but those truths that God wished to see included in the Scripture, and which are important to our salvation, are placed there without error... the Bible is not inerrant in detail, but God has ensured that no substantial errors, which mislead us about the nature of salvation, are to be found in Scripture.
