It happened that, prompted by zeal and affection, he went on one occasion in 391 to Hippo, which was on the Mediterranean Sea five leagues from Carthage, and the site of the present Bona, for the purpose of inducing a certain friend to join him in his solitude. While here he entered the church where the holy bishop, Valerius, was preaching to the people and complaining of his sad need of a priest to aid him in his duties, and especially to exercise the office of preaching, since an impediment in his speech rendered that duty very difficult and extremely painful for him. Preaching was the exclusive function of the bishop. And when Augustine as a priest assumed the duty, he was the first in priest's orders who had ever preached in presence of a bishop. And it was in that capacity that he arose in the Council of Hippo (393) and delivered his famous discourse on "Faith and its Creed." As Augustine entered the church while the bishop was making the above complaint, the congregation, who recognized him (for his fame had spread over all Africa), immediately, as if by divine inspiration, proposed him for the office of priest. Valerius was of course overjoyed; and after a short time which the saint requested for preparation, he was ordained and attached to the church of Hippo. The esteem in which the new priest was held, his apostolic labors, his eloquence, his piety, soon impelled the aged bishop to raise his sacerdotal co-laborer to the episcopal dignity and associate him still more closely with himself in the government of the See of Hippo. He was accordingly consecrated a little before Christmas of the year 395. And the subsequent thirty-five years were the busiest, the most arduous, and the most fruitful of his long and eventful career. His energy was indefatigable and extended in every direction. The religious movements of his time brought into play all the resources of his mind and heart. He combated heresies and reclaimed heretics. His correspondence embraced a multitude of subjects and was carried on with various parts of the Church. His zeal in preaching never knew rest, and his efforts in instructing the ignorant were ceaseless. He established centres of religious life for men and women, and composed for them a rule of life and spirit and principles that have not yet died. He was alive to the necessity of a zealous and energetic clergy whom he wished trained in the spirit and teachings of the Gospel maxims and counsels, and therefore formed the nucleus of a monastic clergy. He had begun the realization of this idea in the community which he established at Hippo just after his ordination as priest, and he perfected it when he was made bishop. Ten of those whom he trained in this his first monastery, became bishops of the various sees of Africa, including Alypius, who was sent to Tagasta, Possidius, his first biographer, and Fortunatus, who was his successor in the See of Hippo.
