Catholics all over the world are celebrating the Assumption of the Blessed Virgin Mary body and soul into heaven. The holy day of obligation, which is called the Dormition of the Theotokoes in Eastern Churches, became Catholic Church dogma in 1950. However, the belief is traced back to the Apostle Thomas who opened Mary’s tomb and found it empty. Tim Harfmann reports from the Cathedral Basilica of St. James in downtown Brooklyn, where the Assumption Mass is offered.
