Jean-Baptiste-Marie Vianney, T.O.S.F. (8 May 1786 – 4 August 1859), commonly known in English as St. John Vianney, was a French parish priest who is venerated in the Catholic Church as a saint. He is known as the patron saint of parish priests. He is often referred to as the “Curé d’Ars” (i.e., Parish Priest of Ars), internationally known for his priestly and pastoral work in his parish in Ars, France, because of the radical spiritual transformation of the community and its surroundings. Catholics attribute this to his saintly life, mortification, his persevering ministry in the sacrament of confession, and his ardent devotion to the Blessed Virgin Mary. His feast day is 4 August.
Tradition of oils
The tradition of anointing with sacred oil is very old indeed. It is used in sacraments and also as a devotional practice. The sick person is invited to apply oil on the part of their body they want healed. As they do so, they are asked to pray to whomever the oil is dedicated to. The Irish blessings oils do not have miraculous power. It is God who has the power to heal. Applying the oil while praying are important ways for us to express our faith in God’s power. Moreover, by doing so we place our trust in God.
