Saint Columba, one of the Twelve Apostles of Ireland, once wished to construct a chapel on the island of Iona, off the west coast of Scotland. However, whatever was built each day, was destroyed each night. It seemed that the task was impossible.
Eventually, a voice spoke to Saint Columba, and told him that the chapel could only be constructed were someone buried alive in the foundation. Columba’s son, Odhran, volunteered himself, was thusly buried, and the chapel was duly completed.
One day, however, Odhran pushed his head through the floor, and said that there was no heaven or hell, as people speak of them. Alarmed, Saint Columba had Odhran’s body removed from the foundation, and properly buried in consecrated ground, lest Odhran reveal more secrets of the afterlife. After this burial, Odhran never bothered the people of Iona again.
