Thaddeus (Jude) the Apostle & Brother of Our Lord
The Apostle Jude was of the choir of the Twelve, and by Luke was called Jude, the brother of James the Brother of God (Luke 6:16; Acts 1:13), and therefore also a kinsman of the Lord according to His humanity. But by Matthew (10:3), he is called Lebbaeus, surnamed Thaddeus (he is not the Thaddeus who healed the suffering of Abgar, as Eusebius says in his Eccl. Hist., 1:13; see Aug. 21). Saint Jude preached in Mesopotamia, Arabia, Idumea, and Syria, and, it is said, completed the path of his divine apostleship by martyrdom in Beirut in the year 80. Written after the destruction of Jerusalem by Titus, his is the last of the Catholic (General) Epistles to the believing Jews in the Diaspora. His name (a variant of Judah) means "Praise."
Apolytikion in the First Tone
We know thee as a kinsman of Christ and we laud thee with sacred hymns and songs as a most steadfast Martyr who trampled on error and who courageously kept the Faith. As we celebrate today thy holy remembrance, we receive forgiveness of our sins and transgressions, O Jude, through thy holy prayers.
Kontakion in the First Tone
Sprung from a noble root, thou art risen before us, a branch bestowed by God, ever feeding the whole world upon the fruits of thy words, O eyewitness of God the Lord, O thou brother of our God, and Christ's all-wise herald, who hast taught the Lord's pure Orthodox Faith to all men, initiate of His grace.
