(Augustine) soon embraced a way of life that brought (Monica) further grief, as he fathered a child out of wedlock in 372. One year later, he began to practice the occult religion of Manichaeism.
In her distress and grief, Monica initially shunned her oldest son. However, she experienced a mysterious dream that strengthened her hope for Augustine’s soul, in which a messenger assured her: “Your son is with you.” After this experience, which took place around 377, she allowed him back into her home, and continued to beg God for his conversion.
But this would not take place for another nine years. In the meantime, Monica sought the advice of local clergy, wondering what they might do to persuade her son away from the Manichean heresy. One bishop, who had once belonged to that sect himself, assured Monica that it was “impossible that the son of such tears should perish.”
These tears and prayers intensified when Augustine, at age 29, abandoned Monica without warning as she passed the night praying in a chapel. Without saying goodbye to his mother, Augustine boarded a ship bound for Rome. Yet even this painful event would serve God’s greater purpose, as Augustine left to become a teacher in the place where he was destined to become a Catholic.
Under the influence of the bishop St. Ambrose of Milan, Augustine renounced the teaching of the Manichees around 384. Monica followed her son to Milan, and drew encouragement from her son’s growing interest in the saintly bishop’s preaching. After three years of struggle against his own desires and perplexities, Augustine succumbed to God’s grace and was baptized in 387. [original post]
Then we went in to my mother, and told her what happened, to her great joy. We explained to her how it had occurred — and she leaped for joy triumphant; and she blessed thee, who art “able to do exceedingly abundantly above all that we ask or think.”[266] For she saw that thou hadst granted her far more than she had ever asked for in all her pitiful and doleful lamentations. For thou didst so convert me to thee that I sought neither a wife nor any other of this world’s hopes, but set my feet on that rule of faith which so many years before thou hadst showed her in her dream about me. And so thou didst turn her grief into gladness more plentiful than she had ventured to desire, and dearer and purer than the desire she used to cherish of having grandchildren of my flesh.
