It is clear that suspicion can provide a creative spur to religious self understanding.[33] Like a scalpel, it cuts deep into the religious conscience but it can be a source of insight which feeds continuing dialogue. It is also clear that suspicion can clearly show up profound differences between the parties but at least mutual understanding has been advanced. In this paper, I have tried to show that the notion of idolatry in both philosophy and theology provides a ‘rhetorical space’ for dialogue between faith and its interrogators and I have used the metaphor of the scalpel to indicate the cost of self reflexivity which is the price of fruitful dialogue.
