From the Prologue of Ochrid
The commemoration of this great Apostle and Evangelist is celebrated on September 26. But on May 8 is remembered the miracle manifested from his grave. When John was more than one hundred years old, he took seven of his disciples, went out of Ephesus, and commanded the disciples to dig a grave in the form of a cross. Then the elder descended alive into that grave and was buried. When the faithful later opened John's grave, they did not find the body in the tomb. And on May 8 of every year a certain dust would rise from his grave, by which the sick were healed of various diseases.
