The irony is that at 29, Jean-Marie Vianney was ordained over the objections of many Catholics in his area, and only after his superiors decided that his zeal and devotion compensated for his "academic under-qualification." He was thought to be so incompetent that he was put under the direction of Fr. Balley, who first recognized and encouraged his vocation. After Fr. Balley's death, Fr. Vianney was appointed parish priest in the small and obscure village of Ars. There he began visiting his parishioners; ministering to the sick and poor; championing campaigns against drinking, dancing and immodest dress, and establishing an orphanage for destitute girls, which became a model for similar institutions throughout France.
In the process of being declared a saint of the Roman Catholic Church, miracles were attributed through his intercession. However, some feel the greatest miracle was his life, itself. For forty years his food and sleep were insufficient to sustain life. Yet he labored incessantly, with unfailing humility, gentleness, patience, and cheerfulness, in service to the people of God. His life is a reminder that everyone, no matter what their status in life, is capable of doing great things in God's name.
Fr. Vianney was canonized in 1925 by Pope Pius XI, and made patron saint of clergy throughout the world in 1929. His feast day is August 4th.
