Encouraged Faith in Christ
The story of Jesus responding personally to a king made Christianity feel personal and accessible.
It suggested that Jesus cared about rulers and nations, not just individuals.
Helped Spread Christianity in Edessa
The letter and the legend of Thaddeus (Addai) healing King Abgar likely encouraged many to accept Christianity.
Whether historical or not, it strengthened the Christian movement in Edessa, which became a major center of early Christianity.
Laid the Foundation for a Christian Kingdom
The letter’s influence helped establish Edessa as a Christian stronghold, paving the way for kings like Abgar VIII and Abgar IX to rule as Christian monarchs.
Edessa became a hub for Syriac Christianity, producing important texts like the Peshitta (Syriac Bible).
Inspired Future Christian Converts
Later Christian missionaries and writers referenced the story to show that even rulers needed Christ.
It reinforced the idea that Christianity was not just a faith of the poor and oppressed but could also reach kings and empires.
Did God Use It?
Even if the letter was a later creation, God still used it to bring people to Christ. Many historical writings contain elements of legend, but the truth of Jesus' power, healing, and salvation remains unchanged.
