It may appear surprising that a gifted student like Augustin did not finish his rhetoric course sooner. But after his terms at Madaura, he had lost nearly a year at Thagaste. Besides, the life of Carthage had so many charms for him that doubtless he was in no hurry to leave. However that may be, the moment was now come for him to make up his mind about his career. The wishes of his parents, the advice of his masters, as well as his own ambitions and qualities, urged him, as we know, to become a barrister. But now, suddenly, all his projects for the future changed. Not only did he give up the law, but at the very moment when all appeared to smile on him, at the opening of his youth, he left Carthage to go and bury himself as a teacher of grammar in the little free-town his birthplace.

As he has neglected to give any explanation of this sudden determination, we are reduced to conjectures. It is likely that his mother was bothered about household expenses and could no longer afford to keep him at Carthage. Besides, she had other children, a son and daughter, to start in life. Augustin was on the point of being, if not poor, at least very hard up. He must do something to earn his living, and as quickly as possible. In these conditions, the quickest way out of the difficulty was to sell to others what he had bought from his masters. To live, he would open a word-shop, as he calls it disdainfully. But as he had only just ceased to be a student, he could not dream of becoming a professor in a great city such as Carthage, and setting himself up in rivalry to so many celebrated masters. The best thing he could do, if he did not want to vegetate, was to fall back on some more modest post. Now his protector, Romanianus, wanted him to go to Thagaste. This rich man had a son almost grown up, whom it was necessary to put as soon as possible in the hands of a tutor. Augustin, so often helped by the father, was naturally thought of to look after the youth. Furthermore, Romanianus, who appreciated Augustin's talent, must have been anxious to attract him to Thagaste and keep him there. With an eye to the interests of his free-town, he desired to have such a shining light in the place. So he asked this young man, whom he patronized, to return to his native district and open a grammar school. He promised him pupils, and, above all, the support of his influence, which was considerable, Monnica, as we may conjecture, added her entreaties to those of the great head of the Thagaste municipality. Augustin yielded.

Did it grieve him very much to make up his mind to this exile? It must have been extremely hard for a young man of twenty to give up Carthage and its pleasures. Moreover, it is pretty nearly certain that at this time he had already started that connection which was to last so long. To leave a mistress whom he loved, and that in all the freshness of a passion just beginning—one wonders how he was able to make up his mind to it. And yet he did leave, and spent nearly a year at Thagaste.

One peculiar mark of the youth, and even of the whole life of Augustin, is the ease with which he unlearns and breaks off his habits—the sentimental as well as the intellectual. He used up a good many doctrines before resting in the Catholic truth; and even afterwards, in the course of a long life, he contradicted and corrected himself more than once in his controversies and theological writings. His Retractations prove this. One might say that the accustomed weighs on him as a hindrance to his liberty; that the look of the places where he lives becomes hateful to him as a threat of servitude. He feels dimly that his true country is elsewhere, and that if he must settle anywhere it is in the house of his Heavenly Father. Inquietum est cor nostrum, donec requiescat in te…. "Restless are our hearts, O my God, until they rest in Thee." Long before St. Francis of Assisi, he practised the mystic rule: "As a stranger and a pilgrim." It is true that in his twentieth year he was very far from being a mystic. But he already felt that restlessness which made him cross the sea and roam Italy from Rome to Milan. He is an impulsive. He cannot resist the mirages of his heart or his imagination. He is always ready to leave. The road and its chances tempt him. He is eager for the unknown. He lets himself be carried in delight by the blowing wind. God calls him; he obeys without knowing where he goes. This unsettled young man, halting between contrary passions, who feels at home nowhere, has already the soul of an apostle.

This changeableness of mood was probably the true cause of his departure for Thagaste. But other more apparent reasons, reasons more patent to a juvenile consciousness, guided him also. No doubt he was not sorry to reappear in his little town, although he was so young, with the importance and authority of a master. His former companions were going to become his pupils. And then the Manichees had fanaticized him. Carried away by the neophyte's bubbling zeal, elevated by his triumphs at the public meetings in Carthage, he meant to shine before his fellow-countrymen, and perhaps convert them. He departed with his mind made up to proselytize. Let us believe also, that in spite of his dissolute life, and the new passion that filled his heart, he did not come back to Thagaste without an affectionate thought at the back of his head for his mother.

The reception that Monnica had in reserve for him was going to surprise him considerably. Since her widowhood, the wife of Patricius had singularly advanced in the way of Christian perfection. The early Church not only offered widows the moral help of its sacraments and consolations, it also granted a special dignity with certain privileges to those who made a vow to refrain from sex-intercourse. They had in the basilicas, even as the consecrated virgins, a place of honour, divided from that of the other matrons by a balustrade. They wore a special dress. They were obliged to a conduct which would shew them worthy of all the outer marks of respect which surrounded them. The austerity of Monnica had increased with the zeal of her faith. She set an example to the Church people at Thagaste. Docile to the teachings of her priests, eager to serve her brethren, multiplying alms as much as she could with her straitened means, she was unfailing at the services of the Church. Twice daily, morning and evening, she might be seen, exact to the hour of prayer and sermon. She did not go there, her son assures us, to mingle in cabals and the gossip of pious females, but to hear God's word in homily, and that God might hear her in prayer.

The widow compelled all who were about her to the same severe rule which she herself observed. In this rigid atmosphere of his home, the student from Carthage, with his free, fashionable airs, must have caused a painful astonishment. Monnica felt at once that she and her son understood each other no longer. She began by remonstrating with him. Augustin rebelled. Things got worse when, with his presumption of the young professor new-enamelled by the schools, the harsh and aggressive assurance of the heresiarch, he boasted as loud as he could of being a Manichee. Monnica, deeply wounded in her piety and motherly tenderness, ordered him to give up his errors. He refused, and only replied by sarcasms to the poor woman's complaints. Then she must have believed that the separation was final, that Augustin had committed an irreparable crime. Being an African Christian, absolute in her faith and passionate for its defence, she regarded her son as a public danger. She was filled with horror at his treason. It is possible, too, that guided by the second-sight of her affection, she saw clearer into Augustin's heart than he did himself. She was plunged in sorrow that he mistook himself to this extent, and refused the Grace which desired to win him to the Catholic unity. And as he was not content with losing himself, but also drew others into peril—disputing, speech-making before his friends, abusing his power of language to throw trouble into consciences—Monnica finally made up her mind. She forbade her son to eat at her table, or to sleep under her roof. She drove him from the house.

This must have been a big scandal in Thagaste. It does not appear, however, that Augustin cared much. In all the conceit of his false knowledge, he had that kind of inhumanity which drives the intellectual to make litter of the sweetest and deepest feelings as a sacrifice to his abstract idol. Not only did he not mind very much if his apostasy made his mother weep, but he did not trouble, either, to reconcile the chimeras of his brain with the living reality of his soul and the things of life. Whatever he found inconvenient, he tranquilly denied, content if he had talked well and entangled his adversary in the net of his syllogisms.

Put in interdict by Monnica, he simply went and quartered himself on Romanianus. The sumptuous hospitality he received there very soon consoled him for his exile from his home. And if his self-esteem had been affronted, the pride of living familiarly with so important a personage was, for a vain young man, a very full compensation.

In fact, this Romanianus roused the admiration of the whole country by his luxury and lavish expenditure. He was bound to ruin himself in the long run, or, at any rate, to raise up envious people bent upon his ruin. Being at the head of the Decurions, he was the protector, not only of Thagaste, but of the neighbouring towns. He was the great patron, the influential man, who had nearly the whole country for his dependents. The town council, through gratitude and flattery, had had his name engraved upon tables of brass, and had put up statues to him. It had even conferred powers on him wider than municipal powers. The truth is that Romanianus did not dole out his benefactions to his fellow-citizens. He gave them bear-fights and other spectacles till then unknown at Thagaste. He did not grudge public banquets, and every day a free meal was to be got at his house. The guests were served plentifully. After having eaten his dinner, they dipped in the purse of the host. Romanianus knew the art of doing an obliging thing discreetly, and even how to anticipate requests which might be painful. So he was proclaimed unanimously, "the most humane, the most liberal, the most polite and happiest of men."
