Conflict with successive Roman emperors shaped Athanasius's career. In 325, at the age of 27, Athanasius began his leading role against the Arians as his bishop's assistant during the First Council of Nicaea. Roman emperor Constantine the Great had convened the council in May–August 325 to address the Arian position that the Son of God, Jesus of Nazareth, is of a distinct substance from the Father. Three years after that council, Athanasius succeeded his mentor as archbishop of Alexandria. In addition to the conflict with the Arians (including powerful and influential Arian churchmen led by Eusebius of Nicomedia), he struggled against the Emperors Constantine, Constantius II, Julian the Apostate and Valens. He was known as "Athanasius Contra Mundum" (Latin for Athanasius Against the World). More on Saint Athanasius of Alexandria
Arianism is a nontrinitarian belief which asserts that Jesus Christ is the Son of God, but is entirely distinct from and subordinate to God the Father. Arianism is defined as those teachings attributed to Arius, which are in opposition to current mainstream Christian teachings on the nature of the Trinity and the nature of Christ. It was first attributed to Arius (c. AD 250–336), a Christian presbyter in Alexandria, Egypt. The Arian concept of Christ is that the Son of God did not always exist, but was created by—and is therefore distinct from—God the Father. This belief is grounded in the Gospel of John (14:28) passage: "You heard me say, 'I am going away and I am coming back to you.' If you loved me, you would be glad that I am going to the Father, for the Father is greater than I." More on Arianism
Saint Nicholas (15 March 270 – 6 December 343), also called Nikolaos of Myra, was a historic 4th-century Christian saint and Greek Bishop of Myra, in modern-day Demre, Turkey). He had a reputation for secret gift-giving, such as putting coins in the shoes of those who left them out for him, a practice celebrated on his feast day―St Nicholas Day (6 December, and thus became the model for Santa Claus, whose modern name comes from the Dutch Sinterklaas, itself from a series of elisions and corruptions of the transliteration of "Saint Nikolaos". His reputation evolved among the faithful, as was common for early Christian saints. In 1087, part of his relics (about half of his bones) were furtively transported to Bari, in Apulia, Italy; for this reason, he is also known as Nikolaos of Bari. The remaining bones were taken to Venice in 1100.
Saint Nicholas is the patron saint of sailors, merchants, archers, repentant thieves, children, brewers, pawnbrokers and students in various cities and countries around Europe. More on Saint Nicholas
Saint Charalambos was an early Christian bishop in Magnesia, a region of Asia Minor. He lived during the reign of Septimius Severus (193-211), when Lucian was Proconsul of Magnesia. It is believed that at the time of his martyrdom in 202, Charalambos was 113 years old.
Charalambos spread the Gospel in that region for many years. However, when news of his preaching reached the authorities of the area, the proconsul Lucian and military commander Lucius, the saint was arrested and brought to trial, where he confessed his faith in Christ and refused to offer sacrifice to idols.
Despite his advanced age, he was tortured mercilessly. They lacerated his body with iron hooks, and scraped all the skin from his body. The saint had only one thing to say to his tormentors: "Thank you, my brethren, for scraping off the old body and renewing my soul for new and eternal life."
More tortures, the legend says, were wrought upon the saint after he was brought to Septimius Severus himself. Condemned to death and led to the place of execution, Charalambos prayed that God grant that the place where his relics would repose would never suffer famine or disease. After praying this, the saint gave up his soul to God even before the executioner had laid his sword to his neck. Tradition says that Severus' daughter Gallina[4] was so moved by his death, that she was converted and buried Charalambos herself. More on Saint Charalambos
