Could you tell me what happened with St. Nectarios - I don't think I've heard the story.
St. Nektarios was given a reliquary Cross by his grandmother which contained a splinter of the True Cross. As an adolescent,St. Nektarios was once crossing the Mediterranian on his way to the Holy Land when a storm blew up and threated to capsize the ship. He took the Cross from around his neck, tied it to his belt and immersed it in the sea praying for salvation. The sea immediatley calmed and the danger passed, but when he lifted up his belt, the Cross was gone. When the ship arrived in Jaffa, for two hours before reaching the port, the sailors could hear a strange knocking sound in the bilges of the ship. The knocking sound continued when the ship was in port, and the Captain ordered the sailors to inspect the hull. The divers found St. Nektarios' Cross stuck to the hull of the ship, and managed to return it to him as he was disembarking. He wore this Cross throughout the rest of his life, and it is sometimes dypicted in his Icons.
