I wrote some time ago in reply to the questions of your reverence, but I did not send the letter, partly because from my long and dangerous illness I had not time to do so; partly because I had no one to send with it.  I have but few men with me who are experienced in travelling and fit for service of this kind.  When you thus learn the causes of my delay, forgive me.  I have been quite astonished at your readiness to learn and at your humility.  You are entrusted with the office of a teacher, and yet you condescend to learn, and to learn of me, who pretend to no great knowledge.  Nevertheless, since you consent, on account of your fear of God, to do what another man might hesitate to do, I am bound for my part to go even beyond my strength in aiding your readiness and righteous zeal.
