Mass of Consecration of Dalia Zakhary

All are invited to join us for the Mass of Consecration of Dalia Zakhary to a life of Virginity Lived in the World on Saturday, June 15 @10:30AM at Christ Cathedral.

Celebrated by Bishop Kevin Vann, this special Mass marks a significant moment for our diocese as Dalia will be the first woman to be consecrated in the Diocese of Orange as a consecrated virgin living in the world.

This ancient vocation existed in the early Church, lived out by the first virgin martyrs, St. Cecilia & St. Agnes, and has since been revised by the Second Vatican Council. Today, over 5,000 women have been called to this vocation worldwide and we are honored to witness Dalia Zachary dedicate herself to this community.
