In March 2002, Shabir Ally and William Lane Craig held a truly remarkable series of four debates at four Canadian universities on four questions distinguishing Christianity and Islam.

The third of these debates was held at McMaster University in Hamilton, Ontario on the topic, "The Concept of God in Islam and Christianity."

Dr. Craig argues for a Trinitarian concept of God and objects that the Islamic concept involves inadequate doctrines of divine goodness and omnipotence, while Ally argues that the primitive Christian concept of God was Unitarian and that the Islamic conception of God is not morally defective.
