He was born of a Christian family in Damascus in the second half of the seventh century, where his father was a high official under the Umayyad caliph; a post which he inherited. When the Iconoclast movement (seeking to prohibit the veneration of icons) gained acceptance in the Byzantine court, John, being under Muslim rather than Byzantine rule, was able to write effective treatises attacking Iconoclasm and attacking the emperor for supporting it. At about this time he retired to the monastery of Saint Sabas near Jerusalem, where he became a monk and was ordained. He died in the middle of the eighth century.
