8 I have heard from the brethren that you are writing a treatise against the Pagans: if we have any claim on your heart, send it at once to us to read. For your heart is such an oracle of divine truth, that we expect from it answers which shall satisfactorily and clearly decide the most prolix debates. I understand that your Holiness has the books of the most blessed father Ambrose, of which I long greatly to see those which, with much care and at great length, he has written against some most ignorant and pretentious men, who affirm that our Lord was instructed by the writings of Plato.
