Comparative theology is a relatively new discipline within theology, which holds together "comparative" and "theology" in creative tension. It represents a particular type of theological practice committed to deep interreligious learning ("comparative") while staying rooted in a particular religious tradition ("theology"). Moreover, while many of its proponents come from the Christian religious tradition, it can have as a starting point the theology of any religious tradition.

Keith Ward is an English philosopher and theologian. He is a fellow of the British Academy and a priest of the Church of England. He was a canon of Christ Church, Oxford, until 2003. Comparative theology and the relationship between science and religion are two of his main topics of interest.
