Pope Nicholas I. being informed of this affair, wrote to Hincmar, and blamed his proceedings. "You ought," says he, "to honor the memory of St. Peter, and await our judgment, even although Rotade had not appealed." And in another letter on the same matter, he threatens Hincmar with excommunication, if he does not restore Rotade. That pope did more. Rotade having arrived at Rome, he declared him acquitted in a council held on Christmas eve, 864; and dismissed him to his see with letters. That which he addressed to all the bishops is worthy of notice, and is as follows: "What you say is absurd, that Rotade, after having appealed to the holy see, changed his language and submitted himself anew to your judgment. Even although he had done so, it would have been your duty to set him right, and teach him that an appeal never lies from a superior judge to an inferior one. But even although he had not appealed to the holy see, you ought by no means to depose a bishop without our participation, in prejudice of so many decretals of our predecessors; for, if it be by their judgment that the writings of other doctors are approved or rejected, how much more should that be respected which they have themselves written, to decide on points of doctrine and discipline. Some tell you that these decretals are not in the book of canons; yet those same persons, when they find them favorable to their designs, use both without distinction, and reject them only to lessen the power of the holy see. If the decretals of the ancient popes are to be rejected because they are not contained in the book of canons, the writings of St. Gregory, and the rest of the fathers, must, on the same principle, be rejected also, and even the Holy Scriptures themselves." "You say," the pope continues, "that judgments upon bishops are not among the higher causes; we maintain that they are high in proportion as bishops hold a high rank in the church. Will you assert that it is only metropolitan affairs which constitute the higher causes? But metropolitans are not of a different order from bishops, and we do not demand different witnesses or judges in the one case, from what are usual in the other; we therefore require that causes which involve either should be reserved for us. And, finally, can anyone be found so utterly unreasonable as to say that all other churches ought to preserve their privileges, and that the Roman Church alone should lose hers?" He concludes with ordering them to receive and replace Rotade.
