Context: True Christianity at its most profound is as good as you get. … I think I've been lucky in the period which I've lived through because obviously I would have been for the chop in earlier days. The Inquisition would have rooted me out; even in the 19th century I would probably have been had up by a Bishop and asked to change my views, or to keep them to myself etc.... I think that so much of our Christian beliefs … are an attempt to convey through language something which is unsayable.
