Saint John of Damascus was a revered Eastern monk and theological doctor, whose works have become the principal textbook of Greek Orthodox theology. Also known for his fight against Iconoclasm, he is often referred as the last of the Church Fathers. But sadly, little is known about his life because his first biography was written almost two hundred years after his death, making it difficult to determine the chronology of his life and authenticity of many events. Nonetheless, it is certain that he was born into an influential Christian family in Damascus and was educated in the scholarly traditions of Latin Christianity. Also aware of Islamic traditions, he eventually began his career at the fiscal administration at the court of the Caliph, but gave it up to lead a monistic life at Mar Saba monastery near Jerusalem, where he spent rest of his life, authoring around 150 important texts and many hymns. His feast day falls on 4 December.
