This is the main feast day of St. John the Theologian, on which we celebrate the falling asleep of the holy, glorious, all-laudable Apostle and Evangelist.
On May 8, we commemorate the miracle that took place each year in Ephesus, on which a type of dust or powder called manna poured forth from his tomb. The manna was used by the faithful for healing sicknesses of both soul and body.
