When Ambrose was informed of the massacre of Thessalonica, his mind was filled with horror and anguish. He retired into the country to indulge his grief, and to avoid the presence of Theodosius. But as the archbishop was satisfied that a timid silence would render him the accomplice of his guilt, he represented, in a private letter, the enormity of the crime; which could only be effaced by the tears of penitence. The episcopal vigor of Ambrose was tempered by prudence; and he contented himself with signifying an indirect sort of excommunication, by the assurance, that he had been warned in a vision not to offer the oblation in the name, or in the presence, of Theodosius; and by the advice, that he would confine himself to the use of prayer, without presuming to approach the altar of Christ, or to receive the holy eucharist with those hands that were still polluted with the blood of an innocent people. The emperor was deeply affected by his own reproaches, and by those of his spiritual father; and after he had bewailed the mischievous and irreparable consequences of his rash fury, he proceeded, in the accustomed manner, to perform his devotions in the great church of Milan. He was stopped in the porch by the archbishop; who, in the tone and language of an ambassador of Heaven, declared to his sovereign, that private contrition was not sufficient to atone for a public fault, or to appease the justice of the offended Deity.

But the archbishop, consulting the maxims of religious policy, granted some indulgence to the rank of his illustrious penitent, who humbled in the dust the pride of the diadem; and the public edification might be admitted as a weighty reason to abridge the duration of his punishment. It was sufficient, that the emperor of the Romans, stripped of the ensigns of royalty, should appear in a mournful and suppliant posture; and that, in the midst of the church of Milan, he should humbly solicit, with sighs and tears, the pardon of his sins. In this spiritual cure, Ambrose employed the various methods of mildness and severity. After a delay of about eight months, Theodosius was
