One day some of the brethren came to see Abba Antony, and among them was Abba Joseph. Wishing to test them, the old man mentioned a text from Scripture, and starting with the youngest he asked them what it meant.
Each explained it the best he could. But to each one the old man said, ‘You have not yet found the answer.’
Last of all he said to Abba Joseph, ‘And what do you think the text means?’
He replied, ‘I do not know.’
Then Abba Antony said, ‘Truly, Abba Joseph has found the way, for he said: I do not know.’”— The Sayings of the Desert Fathers
