Here's one of my favourite theologians putting miserable Christians and arid theology in their place:
How could Christianity have become such a universal power if it had always been as sullen as today's humourless and anguished Protestantism, or as grumpy as the super-organised and super-scholasticised Catholicism about us?...It is not dry manuals (full as these may be of unquestionable truths) that express with plausibility for the world the truth of Christ's Gospel; it is the existence of the saints who have been grasped by Christ's Holy Spirit. And Christ himself foresaw no other kind of apologetics."
