to John, Bishop of the City of Ravenna.
Gregory to his most reverend and most holy brother and fellow-bishop, John.
With kind and humble intent thou reprovest me, dearest brother, for having wished by hiding myself to fly from the burdens of pastoral care; as to which, lest to some they should appear light, I express with my pen in the book before you all my own estimate of their heaviness, in order both that he who is free from them may not unwarily seek them, and that he who has so sought them may tremble for having got them. This book is divided into four separate heads of argument, that it may approach the reader’s mind by allegations arranged in order—by certain steps, as it were. For, as the necessity of things requires, we must especially consider after what manner every one should come to supreme rule; and, duly arriving at it, after what manner he should live; and, living well, after what manner he should teach; and, teaching aright, with how great consideration every day he should become aware of his own infirmity; lest either humility fly from the approach, or life be at variance with the arrival, or teaching be wanting to the life, or presumption unduly exalt the teaching. Wherefore, let fear temper the desire; but afterwards, authority being assumed by one who sought it not, let his life commend it. But then it is necessary that the good which is displayed in the life of the pastor should also be propagated by his speech. And at last it remains that, whatever works are brought to perfection, consideration of our own infirmity should depress us with regard to them, lest the swelling of elation extinguish even them before the eyes of hidden judgment. But inasmuch as there are many, like me in unskilfulness, who, while they know not how to measure themselves, are covetous of teaching what they have not learned; who estimate lightly the burden of authority in proportion as they are ignorant of the pressure of its greatness; let them be reproved from the very beginning of this book; so that, while, unlearned and precipitate, they desire to hold the citadel of teaching, they may be repelled at the very door of our discourse from the ventures of their precipitancy.
