For some, he is a much-needed voice against an increasingly Godless society, representing the views of a significant but largely silent section of the population.
But for a great many others, Stephen Green, the director of Christian Voice, is a solitary individual, unrepresentative of wider opinion and only given prominence by the willingness of the media to offer him a platform.
