On the Holy Trinity; Doctrinal Treatises; Moral Treatises

“I spent some years in writing fifteen books concerning the Trinity, which is God. When, however, I had not yet finished the thirteenth Book, and some who were exceedingly anxious to have the work were kept waiting longer than they could bear, it was stolen from me in a less correct state than it either could or would have been had it appeared when I intended. And as soon as I discovered this, having other copies of it, I had determined at first not to publish it myself, but to mention what had happened in the matter in some other work; but at the urgent request of brethren, whom I could not refuse, I corrected it as much as I thought fit, and finished and published it, with the addition, at the beginning, of a letter that I had written to the venerable Aurelius, Bishop of Carthage, in which I set forth, in the way of prologue, what had happened, what I had intended to do of myself, and what love of my brethren had forced me to do.”
