Alphonsus, like so many saints, had an excellent father and a saintly mother. Don Joseph de' Liguori had his faults. He was somewhat worldly and ambitious, at any rate for his son, and was rough tempered when opposed. But he was a man of genuine faith and piety and stainless life, and he meant his son to be the same. Even when taking him into society in order to arrange a good marriage for him, he wished Alphonsus to put God first, and every year father and son would make a retreat together in some religious house. Alphonsus, assisted by divine grace, did not disappoint his father's care. 
St. Alphonsus Liguori A pure and modest boyhood passed into a manhood without reproach. A companion, Balthasar Cito, who afterwards became a distinguished judge, was asked in later years if Alphonsus had ever shown signs of levity in his youth. He answered emphatically: "Never! It would be a sacrilege to say otherwise." The Saint's confessor declared that he preserved his baptismal innocence till death. Still there was a time of danger. There can be little doubt but that the young Alphonsus with his high spirits and strong character was ardently attached to his profession, and on the way to be spoilt by the success and popularity which it brought. About the year 1722, when he was twenty-six years old, he began to go constantly into society, to neglect prayer and the practices of piety which had been an integral part of his life, and to take pleasure in the attention with which he was everywhere received. "Banquets, entertainments, theatres," he wrote later on—"these are the pleasures of the world, but pleasures which are filled with the bitterness of gall and sharp thorns. Believe me who have experienced it, and now weep over it." In all this there was no serious sin, but there was no high sanctity either, and God, who wished His servant to be a saint and a great saint, was now to make him take the road to Damascus. In 1723 there was a lawsuit in the courts between a Neapolitan nobleman, whose name has not come down to us, and the Grand Duke of Tuscany, in which property valued at 500,000 ducats, that to say, $500,000 or £100,000, was at stake. Alphonsus was one of the leading counsel; we do not know on which side. When the day came the future Saint made a brilliant opening speech and sat down confident of victory. But before he called a witness the opposing counsel said to him in chilling tones: "Your arguments are wasted breath. You have overlooked a document which destroys your whole case." "What document is that?" said Alphonsus somewhat piqued. "Let us have it." A piece of evidence was handed to him which he had read and re-read many times, but always in a sense the exact contrary of that which he now saw it to have. The poor advocate turned pale. He remained thunderstruck for a moment; then said in a broken voice: "You are right. I have been mistaken. This document gives you the case." In vain those around him and even the judge on the bench tried to console him. He was crushed to the earth. He thought his mistake would be ascribed not to oversight but to deliberate deceit. He felt as if his career was ruined, and left the court almost beside himself, saying: "World, I know you now. Courts, you shall never see me more." For three days he refused all food. Then the storm subsided, and he began to see that his humiliation had been sent him by God to break down his pride and wean him from the world. Confident that some special sacrifice was required of him, though he did not yet know what, he did not return to his profession, but spent his days in prayer, seeking to know God's will. After a short interval—we do not know exactly how long—the answer came. On 28 August, 1723, the young advocate had gone to perform a favourite act of charity by visiting the sick in the Hospital for Incurables. Suddenly he found himself surrounded by a mysterious light; the house seemed to rock, and an interior voice said: "Leave the world and give thyself to Me." This occurred twice. Alphonsus left the Hospital and went to the church of the Redemption of Captives. Here he laid his sword before the statue of Our Lady, and made a solemn resolution to enter the ecclesiastical state, and furthermore to offer himself as a novice to the Fathers of the Oratory. He knew that trials were before him. His father, already displeased at the failure of two plans for his son's marriage, and exasperated at Alphonsus's present neglect of his profession, was likely to offer a strenuous opposition to his leaving the world. So indeed it proved. He had to endure a real persecution for two months. In the end a compromise was arrived at. Don Joseph agreed to allow his son to become a priest, provided he would give up his proposal joining the Oratory, and would continue to live at home. To this Alphonsus by the advice of his director, Father Thomas Pagano, himself an Oratorian, agreed. Thus was he left free for his real work, the founding of a new religious congregation. On 23 October of the same year, 1723, the Saint put on the clerical dress. In September of the next year he received the tonsure and soon after joined the association of missionary secular priests called the "Neapolitan Propaganda", membership of which did not entail residence in common. In December, 1724, he received minor orders, and the subdiaconate in September, 1725. On 6 April, 1726, he was ordained deacon, and soon after preached his first sermon. On 21 December of the same year, at the age of thirty, he was ordained priest. For six years he laboured in and around Naples, giving missions for the Propaganda and preaching to the lazzaroni of the capital. With the aid of two laymen, Peter Barbarese, a schoolmaster, and Nardone, an old soldier, both of whom he converted from an evil life, he enrolled thousands of lazzaroni in a sort of confraternity called the "Association of the Chapels", which exists to this day. Then God called him to his life work.
In April 1729, the Apostle of China, Matthew Ripa, founded a missionary college in Naples, which became known colloquially as the "Chinese College". A few months later Alphonsus left his father's house
