S. AMBROSE ends his letter to his sister with forebodings of more troubles. Nor was he wrong. One of the next steps taken was a challenge to dispute publicly before the Emperor with Auxentius the Arian (so-called) Bishop, with regular umpires (judices) appointed on both sides. This letter is his reply to the Emperor, setting forth his ground for refusing, as he had before done at the time of the Council of Aquileia, to allow laymen to be judges of questions of Faith. (See above, Council of Aquil. § 51, 52, 53.)

TO THE MOST CLEMENT EMPEROR, HIS BLESSED MAJESTY VALENTINIAN, AMBROSE, BISHOP, SENDS GREETING.

1. DALMATIUS the tribune and notary cited me at your Clemency’s bidding, as he alleged, requiring that I also should choose umpires as Auxentius had done. He did not mention the names of those who had been called for, but he added that the trial would take place in the Consistory, and that your pious judgment would decide between us.

2. To this I make, as I consider, a sufficient answer.No one ought to deem me contumacious for asserting what your father of illustrious memory not only declared by word of mouth[108] but sanctioned by his laws; that in a matter of the Faith or of any ecclesiastical ordinance, the judges ought to be qualified for it, both competent by office and qualified by profession: (these are the words of the Rescript), that is to say, he would have Bishops judge Bishops. Moreover if a bishop were accused elsewhere also, and a charge of a moral nature to be examined, this too he willed should be referred to the judgment of Bishops.

3. Who then is it who makes a contumacious answer to your Clemency? He who would have you like your Father, or he who would have you unlike? Unless perhaps some persons count cheaply the opinion of that great Emperor,whose faith has been approved by the constancy of his confession[109], and his wisdom proclaimed by the improved condition of the State.

4. When have you ever heard, most gracious Emperor, that laymen had judged a Bishop in a matter pertaining to the Faith? Does their flattery make us cringe so low as to forget the rights of the priesthood, and suppose that what God has committed to me I should entrust to others? If a layman may teach a Bishop, what will follow? a layman will dispute, and a Bishop listen, a Bishop learn of a layman.Assuredly, if we revert to the volume of Holy Scripture or to the time of old, who is there who will deny that in a cause of the Faith, in a cause, I say, of the Faith, Bishops are wont to judge Christian Emperors, not Emperors to judge Bishops.

5. Hereafter, you will, by God’s favour, reach a more mature age, and then you will judge what kind of Bishop he must be who submits the rights of the priesthood to laymen. Your father, who by God’s favour attained a riper age, used to say: ‘It is not for me to judge between Bishops:’ your Majesty now says, ‘I ought to judge.’ He, although baptized into Christ, considered himself unequal to the weight of so important a judgment; does your Majesty, who have yet to earn for yourself the Sacrament of Baptism, claim to decide concerning the Faith, although still ignorant of the Sacrament of this Faith?

6. But what sort of judges he will have selected we may leave to be guessed, seeing that he fears to disclose their names. Let them come openly, if indeed there be any, to the Church; let them attend together with the people, not to sit as judges, but for every one to prove his own feelings and choose whom he will follow. The cause is concerning the Bishop of that Church; if the people hear him and suppose he has the better of the argument, let them follow his Faith; I shall not be jealous.

7. I forbear to mention that the people themselves have already decided;I do not urge that the Bishop[110] whom they have they demanded from your Majesty’s father; I urge not that your father promised tranquillity for the future if he, having been elected, took upon him the Bishopric. It was in reliance on these promises that I acted.

8. But if he prides himself on the support of any foreigners let him be Bishop in the place whence those come who hold that he should be invested with the name of a Bishop. For I neither acknowledge him as Bishop, nor know whence he comes.
