His uncle was the archbishop of Myra, and he ordained Nicholas and appointed him to be the abbot of a nearby monastery. At the death of the archbishop, Nicholas was chosen to fill the vacancy, and he served in this position until his death. About the time of the persecutions of Diocletian, he was imprisoned for preaching Christianity but was released during the reign of Emperor Constantine.
There are lots of stories surrounding the life of Saint Nicholas, one of which relates Nicholas' charity toward the poor. A certain man, who was the father of three daughters, had lost his fortune, and finding himself unable to support his daughters, he was planning to sell them into slavery. Nicholas heard of the man's intentions and secretly threw three bags of gold through a window into the home, thus providing dowries for the daughters, enabling them to be married. There are other stories of his generosity in giving to others, but he always tried to do it secretly.
After Nicholas' death on December 6 in or around 345, his body was buried in the cathedral at Myra, and a great devotion to him grew up. More and more people visited his tomb to ask for his prayers. His body remained there until 1087, when some sailors from Bari, an Italian coastal town, came and took the relics of the saint and transferred them to their own city. Veneration for Nicholas had already spread throughout Europe as well as Asia, but this occurrence led to a renewal of devotion in the West. Countless miracles were attributed to the saint's intercession. His relics are still preserved in the Basilica of San Nicola in Bari.
O God, who didst adorn thy blessed Bishop Saint Nicholas with power to work many and great miracles: grant, we beseech thee; that by his prayers and merits, we may be delivered from the fires of everlasting torment; through Jesus Christ thy Son our Lord, who liveth and reigneth with thee, in the unity of the Holy Spirit, ever one God, world without end. Amen.
