Pantocrator. (Gr. "He who reigns over all; almighty"). One of the appellations of God. In Orthodox art, Pantocrator is the name of the fresco decorating the center of the dome, depicting Christ as the almighty God and Lord of the Universe.

The Greek word "Pantocrator" is pronounced as pan-toe-krah-tor, with the emphasis on the second syllable.

The icon of Christ "Pantocrator" means "Ruler of the Universe." It is usually painted in the highest part of an Orthodox church (the ceiling or dome) and shows Jesus Christ as the Ruler of both heaven and earth.

Pantocrator is just an alternate Hebrew translation for the word God. That being said, Christ on earth as a human was a teacher, once resurrected the teaching fell to his disciples. His humanity had ended, His divinity complete.

The open book held by Christ Pantocrator typically contains the words "Ego Sum Lux Mundi" which translates to "I am the Light of the World" in Latin. This phrase emphasizes Jesus's role as the divine light and savior of humanity.
