John x. 11. has not even now left us; but is present, and tends and guides, and knows his own, and is known of his own, and, though bodily invisible, is spiritually recognized, and defends his flock against the wolves, and allows no one to climb over into the fold as a robber and traitor; to pervert and steal away, by the voice of strangers, souls under the fair guidance of the truth.  Aye, I am well assured that his intercession is of more avail now than was his instruction in former days, since he is closer to God, now that he has shaken off his bodily fetters, and freed his mind from the clay which obscured it, and holds intercourse naked with the nakedness of the prime and purest Mind; being promoted, if it be not rash to say so, to the rank and confidence of an angel.  This, with your power of speech and spirit, you will set forth and discuss better than I can sketch it.  But in order that, through ignorance of his excellences, your language may not fall very far short of his deserts, I will, from my own knowledge of the departed, briefly draw an outline, and preliminary plan of an eulogy to be handed to you, the illustrious artist of such subjects, for the details of the beauty of his virtue to be filled in and transmitted to the ears and minds of all.
