I was just reading a book that touched on Ancient Rome. The author tried to convey the significance of the Council of Nicaea by comparing it to the furor over Global Warming.

Not odd in the sense that they are intellectually inscrutable but - like people getting excited over the matters theological - that they're emotionally inscrutable.
