The most common translation of Pantocrator is "Almighty" or "All-powerful." In this understanding, Pantokrator is a compound word formed from the Greek words for "all" and the noun "strength" (κρατος). This is often understood in terms of potential power; i.e., able to do anything, or omnipotent. Christians ascribed this title to Jesus of Nazareth.

In the Iconography.
The iconic image of Christ Pantocrator ("Christ, Ruler of All") was one of the first images of Christ developed in the Early Christian Church and remains a central icon of the Eastern Orthodox Church. In the half-length image, Christ holds the New Testament in his left hand and makes the gesture of teaching or of blessing with his right.




In 544 AD, a cloth bearing an image of Jesus was discovered hidden above a gate in Edessa's city walls. Six years later, an icon was produced at St. Catherine's Monastery in the Sinai. See Early History of the Shroud of Turin
