The line of conduct which Ambrose had adopted remained equally clear and straight, whether before or after the promulgation of this edict. It was his duty to use all the means which Christ has given the Church to prevent the profanation of the Basilica. But soon a new question arose for his determination. An imperial message was brought to him to retire from the city at once, with any friends who chose to attend him. It is not certain whether this was intended as an absolute command, or (as his words rather imply) a recommendation on the part of government to save themselves the odium, and him the suffering, of public and more severe proceedings. Even if it were the former, it does not appear that a Christian bishop, so circumstanced, need obey it; for what was it but in other words to say, "Depart from the Basilica, and leave it to us?"--the very order which he had already withstood. The words of Scripture, which bid Christians, if persecuted in one city, flee to another, are evidently, from the form of them, a discretionary rule, grounded on the expediency of each occasion, as it arises. A mere threat is not a persecution, nor is a command; and though we are bound to obey our civil rulers, the welfare of the Church has a prior claim upon our obedience. Other bishops took the same view of the case with Ambrose; and, accordingly, he determined to stay in Milan till removed by main force, or cut off by violence. 2. The reader shall hear his own words in a sermon which he delivered upon the occasion:-- "I see that you are under a sudden and unusual excitement," he said, "and are turning your eyes on me. What can be the reason of this? Is it that you saw or heard that an imperial message had been brought to me by the tribunes desiring me to depart hence whither I would, and to take with me all who would follow me? What! did you fear that I would desert the Church, and, for fear of my life, abandon you? Yet you might have attended to my answer. I said that I could not, for an instant, entertain the thought of deserting the Church, in that I feared the Lord of all more than the Emperor of the day: in truth that, should force hurry me off, it would be my body, not my mind, that was got rid of; that, should he act in the way of kingly power, I was prepared to suffer after the manner of a priest.
