Other early stories tell of him calming a storm at sea, saving three innocent soldiers from wrongful execution, and chopping down a tree possessed by a demon. In his youth, he is said to have made a pilgrimage to Egypt and Palestine. Shortly after his return, he became Bishop of Myra. He was later cast into prison during the persecution of Diocletian, but was released after the accession of Constantine. An early list makes him an attendee at the First Council of Nicaea in 325,

During his life, Nicholas is said to have received visions, including images of Purgatory, which friends ascribed to his lengthy fasts. Prayer for the souls in Purgatory was the outstanding characteristic of his spirituality. Because of this Nicholas was proclaimed patron of the souls in Purgatory, in 1884 by Leo XIII. Towards the end of his life he became ill, suffering greatly, but still continued the mortifications that had been part of his holy life. Nicholas died on September 10, 1305.

He is said to have been imprisoned by Diocletian but afterwards released. He is known for his good deeds. Justinian built the first church known to be dedicated to him, the church of Priscus and St. Nicholas, in Constantinople. The popularity of St. Nicholas caused the sailors of Bari to cross over to Myra to capture his remains from the infidel and rebury them in their native town, where they have since rested. ; St. Nicholas has been venerated in Germany since 12th century. St. Nicholas was

He argues that this desire to help women is most characteristic of fourth-century Christianity, due to the prominent role women played in the early Christian movement, rather than Greco-Roman paganism or the Christianity of Michael the Archimandrite's time in the ninth century, by which point the position of women had drastically declined. In another story, Nicholas is said to have visited the Holy Land. The ship he was on was nearly destroyed by a terrible storm, but he rebuked the waves, causing the storm to subside. Because of this miracle, Nicholas became venerated as the patron saint of sailors and travelers
Title: Saint Nicholas
Content:   After visiting the Holy Land, Nicholas returned to Myra. The bishop of Myra, who had succeeded Nicholas's uncle, had recently died and the priests in the city had decided that the first priest to enter the church that morning would be made bishop. Nicholas went to the church to pray and was therefore proclaimed the new bishop. He is said to have been imprisoned and tortured during the Great Persecution under the Emperor Diocletian (ruled 284–305), but was released under the orders of the Emperor Constantine the Great (ruled 306–337). This story sounds plausible, but is not attested in the earliest sources and is therefore unlikely to be historical. One of the earliest attested 
Title: Saint Nicholas
Content:  Accounts of Saint Nicholas's life agree on the essence of his story, but modern historians disagree regarding how much of this story is actually rooted in historical fact. Traditionally, Nicholas was born in the city of Patara (Lycia et Pamphylia), a port on the Mediterranean Sea, in Asia Minor in the Roman Empire, to a wealthy family of Greek Christians. According to some accounts, his parents were named Epiphanius (Ἐπιφάνιος, Epiphánios) and Johanna (Ἰωάννα, Iōánna), but, according to others, they were named Theophanes (Θεοφάνης, Theophánēs) and Nonna (Νόννα, Nónna). In some accounts, Nicholas's uncle was the bishop of the city of Myra, also in Lycia. Recognizing his nephew's calling, Nicholas's uncle ordained him as a priest.

Content:  he is never mentioned in any writings by people who were actually at the council. Late, unsubstantiated legends claim that he was temporarily defrocked and imprisoned during the council for slapping the heretic Arius. Another famous late legend tells how he resurrected three children, who had been murdered and pickled in brine by a butcher planning to sell them as pork during a famine. Fewer than 200 years after Nicholas's death, the St. Nicholas Church was built in Myra under the orders of Theodosius II over the site of the church where he had served as bishop, and his remains were moved

His work as bishop between 1452 and 1458 – trying to impose reforms and reclaim lost diocesan revenues – was opposed by Duke Sigismund of Austria. The duke imprisoned Nicholas in 1460, for which Pope Pius II excommunicated Sigismund and laid an interdict on his lands. Nicholas returned to Rome, but was never able to return to his bishopric. He died at Todi in Umbria on 11 August 1464. Sigismund's capitulation came a few days after Nicholas's death. Upon his

Hung by the fire to dry, stockings were miraculously filled with gold so the girls could marry. St. Nicholas is said to have brought back to life three children who had been murdered and stored as pickled meat in the house of a wicked butcher. The children carried out church duties thereafter and were rewarded with small gift on December 6. Thomas Nast (1840-1902), who came to America from Germany as a child created the white-bearded Santa Claus with a pack on his back, combining St. Nicholas and Knecht Ruprecht. 
Title: Nicholas of Japan
Content:  During the Russo-Japanese War, Nicholas stayed in Japan. Those days were very difficult for him. His love for the land of his birth conflicted with his duty as the bishop of Japan to support his faithful and to pray for the Japanese Emperor and the Imperial Japanese Army and Navy: in the orthodox liturgy at that time, priests had to explicitly pray not only benediction on the sovereign and his army, but also for the defeat of his enemies in the intercession. Nicholas therefore did not participate in any public services during the war; instead, he encouraged his Japanese faithful to both pray for and to contribute to the Army and Navy. Some encouraged him to go back to Russia, but he refused and worked eagerly for Japanese faithful and Russian prisoners of war. In a letter on the conditions of a camp in Hamadera, Osaka, Nicholas wrote of his astonishment at the Russians soldiers' illiteracy: nine of ten captives could not read. Nicholas sent priests and teachers to camps to educate and care for the captives. His attitude and manners impressed not only the Orthodox faithful but also non-Christians.
