I think I first encountered JAT Robinson (1919-1983) and discussions of his 1963 work 'Honest to God' in the writings of Francis Schaeffer and authors such as Iain Murray of the Banner of Truth. This would have been back in the mid-1990's.
For those unfamiliar with the discussion, Robinson was the Bishop of Woolwich and while in that office he published 'Honest to God' in which he revealed his doubts about conventional theism. It shocked the Christian world at the time (1963) - a bishop who was effectively (at least according to traditional definitions) an agnostic, if not an outright atheist.
