Jerome, another bishop since sainted by the Catholic Church, and Augustine used to write to each other. They lived a long way apart, and their correspondence took place over a number of years. At one point Jerome accuses Augustine of publishing a letter to him to the whole world before it arrived with him. Reading their correspondence is pretty worthwhile (especially if you’re writing an essay for Early Church History).
But this long exchange serves to solidify my opinion that Augustine would totally have blogged.
From Jerome (402 AD):
When my kinsman, our holy son Asterius, subdeacon, was just on the point of beginning his journey, the letter of your Grace arrived, in which you clear yourself of the charge of having sent to Rome a book written against your humble servant. I had not heard that charge; but by our brother Sysinnius, deacon, copies of a letter addressed by some one apparently to me have come hither. In the said letter I am exhorted to sing the παλινωδία, confessing mistake in regard to a paragraph of the apostle’s writing, and to imitate Stesichorus, who, vacillating between disparagement and praises of Helen, recovered, by praising her, the eyesight which he had forfeited by speaking against her. Although the style and the method of argument appeared to be yours, I must frankly confess to your Excellency that I did not think it right to assume without examination the authenticity of a letter of which I had only seen copies, lest perchance, if offended by my reply, you should with justice complain that it was my duty first to have made sure that you were the author, and only after that was ascertained, to address you in reply…
Far be it from me to presume to attack anything which your Grace has written. For it is enough for me to prove my own views without controverting what others hold. But it is well known to one of your wisdom, that every one is satisfied with his own opinion, and that it is puerile self-sufficiency to seek, as young men have of old been wont to do, to gain glory to one’s own name by assailing men who have become renowned. I am not so foolish as to think myself insulted by the fact that you give an explanation different from mine; since you, on the other hand, are not wronged by my views being contrary to those which you maintain. But that is the kind of reproof by which friends may truly benefit each other, when each, not seeing his own bag of faults, observes, as Persius has it, the wallet borne by the other. Let me say further, love one who loves you, and do not because you are young challenge a veteran in the field of Scripture. I have had my time, and have run my course to the utmost of my strength. It is but fair that I should rest, while you in your turn run and accomplish great distances; at the same time (with your leave, and without intending any disrespect), lest it should seem that to quote from the poets is a thing which you alone can do, let me remind you of the encounter between Dares and Entellus, and of the proverb, “The tired ox treads with a firmer step.” With sorrow I have dictated these words. Would that I could receive your embrace, and that by converse we might aid each other in learning!
Augustine (402 AD) responds, denying he wrote a book against Jerome:
I have hesitated whether to give credence or not to a certain report which has reached me; but I felt that I ought not to hesitate as to writing a few lines to you regarding the matter. To be brief, I have heard that some brethren have told your Charity that I have written a book against you and have sent it to Rome. Be assured that this is false: I call God to witness that I have not done this. But if perchance there be some things in some of my writings in which I am found to have been of a different opinion from you, I think you ought to know, or if it cannot be certainly known, at least to believe, that such things have been written not with a view of contradicting you, but only of stating my own views. In saying this, however, let me assure you that not only am I most ready to hear in a brotherly spirit the objections which you may entertain to anything in my writings which has displeased you, but I entreat, nay implore you, to acquaint me with them; and thus I shall be made glad either by the correction of my mistake, or at least by the expression of your goodwill.
It gets a little fiery tomorrow…
