The intellect cannot cope with such paradoxes, though it somehow senses the reality beyond all reality, the truth beyond all truth. Precisely here lies the danger. The mind must never allow itself to be misled into seeming 'comprehension,' into facile sensations or phrases with nothing solid behind them. The whole problem is a mystery, the sacred mystery of the relationship of the triune God to his incarnate Son. We can never penetrate it, and knowledge of this incapacity must dominate our every thought and statement concerning Jesus' life.
--Romano Guardini, The Lord
I think this basic idea is itself almost a commonplace now, so much so that it can become another means of evasion, of "seeming 'comprehension'". So that stern "must dominate" is still needed, and always will be.
