According to some, this Saint was a son of Joseph the Betrothed, born of the wife that the latter had before he was betrothed to the Ever-virgin. Hence he was the brother of the Lord, Who was also thought to be the son of Joseph (Matt. 13: 55). But some say that he was a nephew of Joseph, and the son of his brother Cleopas, who was also called Alphaeus and Mary his wife, who was the first cousin of the Theotokos. But even according to this genealogy, he was still called, according to the idiom of the Scriptures, the Lord's brother because of their kinship.

This Iakovos is called the Less (Mark 15:40) by the Evangelists to distinguish him from Iakovos, the son of Zebedee, who was called the Great. He became the first Bishop of Jerusalem, elevated to this episcopal rank by the Apostles, according to Eusebius (Eccl. Hist., Book II: 23), and was called Obliah, that is, the Just, because of his great holiness and righteousness. Having ascended the crest of the Temple on the day of the Passover at the prompting of all, he bore testimony from there concerning his belief in Jesus, and he proclaimed with a great voice that Jesus sits at the right hand of the great power of God and shall come again upon the clouds of heaven. On hearing this testimony, many of those present cried, "Hosanna to the Son of David." But the Scribes and Pharisees cried, "So, even the just one hath been led astray," and at the command of Ananias the high priest, the Apostle was cast down headlong from thence, then was stoned, and while he prayed for his slayers, his head was crushed by the wooden club wielded by a certain scribe. The first of the Catholic (General) Epistles written to the Jews in the Diaspora who believed in Christ was written by this Iakovos.

These Martyrs contested for piety's sake in the year 524 in Najran, a city of Arabia Felix (present-day Yemen). When Dhu Nuwas, ruler of the Himyarite tribe in south Arabia, and a Judaizer, took power, he sought to blot out Christianity, especially at Najran, a Christian city. Against the counsels of Arethas, chief man of Najran, the city surrendered to Dhu Nuwas, who immediately broke the word he had given and sought to compel the city to renounce Christ. Led by Saint Arethas, hundreds of martyrs, including women, children, and babes, valiantly withstood his threats, and were beheaded and burned. After the men had been slain, all the free-born Christian women of Najran were brought before the tyrant and commanded to abjure Christ or die; yet they rebuked the persecutor with such boldness that he said even the men had not insulted him so contemptuously. So great was their faith that not one woman was found to deny Christ in all Najran, although some of them suffered torments more bitter than most of the men. In alliance with Byzantium, the Ethiopian King Elesbaan liberated Najran from Dhu Nuwas soon after and raised up churches in honour of the Martyrs. Najran became a place of pilgrimage until the rise of Islam a century later. At the end of his life King Elesbaan, who was also called Caleb, retired into solitude as a hermit; he sent his crown to Jerusalem as an offering to the Church of the Holy Sepulchre. He also is commemorated on this day as a saint. Saint Arethas' name in Arabic, Harith, means "plowman, tiller," much the same as "George" does in Greek.

Saint Demetrius was a Thessalonian, a most pious son of pious and noble parents, and a teacher of the Faith of Christ. When Maximian first came to Thessalonica in 290, he raised the Saint to the rank of Duke of Thessaly. But when it was discovered that the Saint was a Christian, he was arrested and kept bound in a bath-house. While the games were under way in the city, Maximian was a spectator there. A certain friend of his, a barbarian who was a notable wrestler, Lyaeus by name, waxing haughty because of the height and strength of his body, boasted in the stadium and challenged the citizens to a contest with him. All that fought with him were defeated. Seeing this, a certain youth named Nestor, aquaintance of Demetrius', came to the Saint in the bath-house and asked his blessing to fight Lyaeus single-handed. Receiving this blessing and sealing himself with the sign of the precious Cross, he presented himself in the stadium, and said, "O God of Demetrius, help me!" and straightway he engaged Lyaeus in combat and smote him with a mortal blow to the heart, leaving the former boaster lifeless upon the earth. Maximian was sorely grieved over this, and when he learned who was the cause of this defeat, he commanded straightway and Demetrius was pierced with lances while he was yet in the bath-house, As for Nestor, Maximian commanded that he be slain with his own sword.

The Feast of the Protection commemorates the appearance of the most holy Theotokos in the Church of Blachernae in Constantinople in the tenth century, as recorded in the life of Saint Andrew the Fool for Christ's sake. While the multitudes of the faithful were gathered in church, Epiphanius, the friend of Saint Andrew, through the Saint's prayers, beheld the Virgin Mary above the faithful and spreading out her veil over them, signifying her unceasing protection of all Christians. Because of this we keep a yearly feast of gratitude, imploring our Lady never to cease sheltering us in her mighty prayers.

In the Greek tradition, this feast is celebrated on October 28, while in the Slavic tradition, this feast is celebrated on October 1.
