Jude the Apostle in the context of "Bartholomew the Apostle"

The Armenian Apostolic Church (Armenian: Հայ Առաքելական Եկեղեցի, romanized: Hay Aṙaqelakan Ékełetsi) is the autocephalous national church of Armenia. Part of Oriental Orthodoxy, it is one of the most ancient Christian churches. The Armenian Apostolic Church uses the Armenian Rite. The Kingdom of Armenia was the first state in history to adopt Christianity as its official religion (under the Armenian Apostolic traditions) during the rule of King Tiridates III, of the Arsacid dynasty in the early 4th century.

According to tradition, the church originated in the missions of Apostles Bartholomew and Thaddeus (Jude) in the 1st century. St. Gregory the Illuminator was the first official primate of the church. It is sometimes referred to as the Armenian Apostolic Orthodox Church, Armenian Church or Armenian Gregorian Church.

The Apostles' Creed (Latin: Symbolum Apostolorum or Symbolum Apostolicum), sometimes titled the Apostolic Creed or the Symbol of the Apostles, is a Christian creed or "symbol of faith".

"Its title is first found c.390 (Ep. 42.5 of Ambrose). ... Th[e present] form seems to have had a Hispano-Gallic origin ...". The creed most likely originated as a development of the Old Roman Symbol: the old Latin creed of the 4th century. It has been used in the Latin liturgical rites since the 8th century and, by extension, in the various modern branches of Western Christianity, including the modern liturgy and catechesis of Roman Catholicism, Evangelical Lutheranism, Reformed (Continental Reformed, Presbyterian, Congregationalist, Calvinistic Methodist and Reformed Baptist traditions), Moravianism, Anglicanism and Methodism.

John 14 is the fourteenth chapter of the Gospel of John in the New Testament of the Christian Bible. It continues Jesus' discussions with his disciples in anticipation of his death and records the promised gift of the Holy Spirit. Jesus speaks individually with Thomas, Philip and Judas (not the Iscariot); throughout this chapter, Jesus' purpose is to strengthen the faith of the apostles. Christians traditionally believe that John composed this Gospel.

The Catholicos of All Armenians (Armenian: Ամենայն Հայոց Կաթողիկոս) is the chief bishop and spiritual leader of Armenia's national church, the Armenian Apostolic Church, and the worldwide Armenian diaspora. The Armenian Catholicos (plural Catholicoi) is also known as the Armenian Pontiff (Վեհափառ, Vehapar or Վեհափառ Հայրապետ, Vehapar Hayrapet) and by other titles. According to tradition, the apostles Saint Thaddeus and Saint Bartholomew brought Christianity to Armenia in the first century. Saint Gregory the Illuminator became the first Catholicos of All Armenians following the nation's adoption of Christianity as its state religion in 301 AD. The seat of the Catholicos, and the spiritual and administrative headquarters of the Armenian Church, is the Mother See of Holy Etchmiadzin, located in the city of Vagharshapat.

The Armenian Apostolic Church is part of the Oriental Orthodox communion. This communion includes the Coptic Orthodox Church of Alexandria, the Ethiopian Orthodox Tewahedo Church, the Syriac Orthodox Church, the Malankara Orthodox Syrian Church, and the Eritrean Orthodox Tewahedo Church.

The Epistle of Jude is the penultimate book of the New Testament and of the Christian Bible. The Epistle of Jude claims authorship by Jude, identified as a servant of Jesus and brother of James (and possibly Jesus), though there is scholarly debate about his exact identity, literacy, and the letter's date. It was most likely written in the late first century, with some considering its authorship pseudepigraphical.

Jude urges believers to defend the faith against false teachers and warns of their destructive consequences by recalling examples of divine judgment on the unbelieving and rebellious. He encourages steadfastness in God's love despite scoffers, uses vivid imagery to describe these opponents, and supports his message by quoting the Book of Enoch. The Epistle of Jude references both canonical books like Zechariah and non-canonical works such as the Book of Enoch and the Assumption of Moses, indicating its author's familiarity with a range of writings. The Epistle of Jude condemns vague opponents—variously interpreted as rebellious leaders, heretics rejecting divine or ecclesiastical authority, proto-Gnostics, or critics of Pauline teachings—but their exact identity remains uncertain due to the epistle's ambiguous and limited descriptions. The Epistle of Jude, a brief, combative, and impassioned letter of 25 verses likely intended as a circular letter to Jewish Christians familiar with Hebrew Bible and Enochian references. It concludes with a doxology.

Jude (alternatively Judas or Judah; Ancient Greek: Ἰούδας) was a "brother" of Jesus according to the New Testament. He is traditionally identified as the author of the Epistle of Jude, a short epistle which is reckoned among the seven general epistles of the New Testament—placed after Paul's epistles and before the Book of Revelation—and considered canonical by Christians. Catholics and Eastern Orthodox Christians believe this Jude is the same person as Jude the Apostle; Catholics hold that Jude was a cousin, but not literally a brother of Jesus, while the Eastern Orthodox hold that Jude is St. Joseph's son from a previous marriage.
