Pope Francis has asked all Christians to recite the Our Father with him at noon, Rome time, which means 7 a.m. EST, for most of our readers.
Also, the Holy Father is offering an Urbi et Orbi address at noon, Rome time, followed by Benediction (which is 7 p.m., EST, for most of our readers in North America), for which he is offering a plenary indulgence.
Oremus pro invicem!
