The moment this was said, small flames, looking like tongues, came down from heaven on to the newcomers heads; by these they were inspired with a desire to know from reason the source of their faith. They exclaimed, 'What is faith but truth? Where is truth in its own light, except in the understanding! If the understanding is in darkness, what is faith then but a sleep-walker, and if it receives confirmation from natural light separated from spiritual light, that faith becomes a bat.' Among the newly arrived was a priest. He on hearing these things from his companions said in an angry voice, 'What has faith to do with the understanding!' The angels replied, 'What is faith without understanding but blind faith?' And then suddenly the small flame dropped from the top of his head to his shoe, and shone here for a while.
