As for this present treatise, which I have thought it proper to address to no other person in preference to yourself, who have taken a kindly and true interest both in our common faith and my character, as a true catholic and a good friend, you will give it to be read or copied by any persons you may be able to find interested in the subject, or may deem worthy to be trusted. In it I have thought proper to repress and confute the presumption of this young man, in such a way, however, as to show that I love him, wishing him to be amended rather than condemned, and to make such progress in the great house which is the catholic Church, whither the divine compassion has conducted him, that he may be therein “a vessel unto honour, sanctified, and meet for the Master’s use, and prepared unto every good work,” both by holy living and sound teaching. But I have this further to say: if it behoves me to bestow my love upon him, as I sincerely do, how much more ought I to love you, my brother, whose affection towards me and whose catholic faith I have found by the best of proofs to be cautious and sober! The result of your loyalty has been, that you have, with a brother’s real love and duty, taken care to have the books, which displeased you, and wherein you found my name treated in a way which ran counter to your liking, copied out and forwarded to me. Now, I am so far from feeling offended at this charitable act of yours, because you did it, that I think I should have had a right, on the true claims of friendship, to have been angry with you if you had not done it. I therefore give you my most earnest thanks. Moreover, I have afforded a still plainer indication of the spirit in which I have accepted your service, by instantly composing this treatise for your consideration, as soon as I had read those books of his.
