Image of Edessa
The Armenian Orthodox Church believes in apostolic succession through the apostles Bartholomew and Thaddeus of Edessa. According to tradition, the latter of the two apostles is said to have cured Abgar V of Edessa of leprosy with the Image of Edessa, leading to his conversion in 30 AD. Thaddaeus was then commissioned by Abgar to proselytize throughout Armenia, where he converted the king Sanatruk's daughter, who was eventually martyred alongside Thaddeus when Sanatruk later fell into apostasy. After this, Bartholomew came to Armenia, bringing a portrait of the Virgin Mary, which he placed in a nunnery he founded over a former temple of Anahit. Bartholomew then converted the sister of Sanatruk, who once again martyred a female relative and the apostle who converted her. Both apostles ordained native bishops before their execution, and some other Armenians had been ordained outside of Armenia by James the Just. Scholars including Bart Ehrman, Han Drijvers, and W. Bauer dismiss the conversion of Abgar V as fiction.
