Recent conversations regarding the nature of divine transcendence and language bring to mind Andrew Louth’s excellent Discerning the Mystery: An Essay on the Nature of Theology (1990). Father Stephen discusses it a bit on his blog, as does Aaron Taylor. But the entire essay is also available online (and shared here).
NB (7/31/2014) I see that Scribd has removed the online version of Louth’s book. You may find it here.
