John-Baptist-Mary Vianney was born at Dardilly near Lyons (France) on May 8th, 1786. After many difficulties, he received holy priesthood in August 1815. He was parish priest of Ars for nearly forty-two years: he became a model for all his brethren in the sacerdotal ministry by his pastoral zeal, and by the unflagging ardour of his prayer and penance. Sitting up to sixteen hours a day in the confessional, he healed souls and sometimes bodies as well. His simple catechism preaching touched the hearts of grown ups as well as those of children. Meanwhile, he chastized his body as an act of reparation and impetration for sinners. He died on August 4th, 1859; he was beatified in 1905 by Pope Pius X, who had been a parish priest, and canonized by Pius XI in 1925.
Os justi meditabitur sapientiam, et lingua ejus loquetur judicium; lex Dei ejus in corde ipsius. * Noli aemulari in malignantibus: neque zelaveris facientes iniquitatem.
The mouth of the just shall meditate wisdom, and his tongue shall speak judgement: the law of his God is in his heart. * Be not emulous of evildoers: nor envy them that work iniquity.
(Psalm 36:30-31,1 from the Introit of Mass)
Omnipotens et misericors Deus, qui beatum Joannem Mariam, pastorali studio et jugi orationis ac poenitentiae ardore mirabilem effecisti: da, quaesumus, ut ejus exemplo et intercessione, animas fratrum lucrari Christo, et cum eis aeternam gloriam consequi valeamus.
Almighty and merciful God, who didst bestow upon blessed John Mary wonderful pastoral zeal and a great fervour for prayer and penance ; grant, we beseech Thee, that by his example and intercession we may be able to gain the souls of our brethren for Christ, and with them attain to everlasting glory.
