Today is the 150th anniversary of the entrance into eternal life of St. John Vianney. St. John Vianney is the patron saint of priests, so today offer a little prayer for all the priests who you have encountered in your life; the priest who baptized you, who heard your first confession, who gave you your first Holy Communion, who witnessed your marriage. And if you really want to make a priest's day, give him a call to wish him a happy feast day and thank him for saying yes to God's call to the priesthood.
Also, during this Year for Priests you can gain a plenary indulgence on this day. For more information you can click on the title to this post or here.
