Sarcasm in theological academe

I can’t believe that having enjoyed myself in a deliciously instructive and educational treatise on the imminence of the Kingdom of God, Joel B Green et al (including I. H. Marshall no less) punctuated the discussion with this: “It is not therefore an exaggeration to say that sometimes the parables have a polemical tone in addition to their usage to illustrate the kingdom of God“. I would have thought: “like duh…” but it is nice to have an almost dead pan sarcasm in such work…

If only I could read on all night.
