Now Jesus Christ is God's Son, in Whom
“dwelleth all the fulness of the Godhead bodily” (Col.2:9).
So how can we affirm that He was seen by both St. John and Daniel?
After the dogma of icon-worship won a victory in the eighth century, it was stated that only what could be seen by the human eye could be depicted. Since Daniel had seen the Ancient of Days, hence He could be depicted on icons. And He was indeed often and profusely thus portrayed. Besides the captions of "The Ancient of Days" and "Jesus Christ" encountered as synonyms on one and the same icon. Moreover Byzantine theologians identified the Ancient of Days and, consequently, Jesus Christ as God, with Whom Israel know as Yahweh:
I AM THAT I AM Ex. 3:14
What then of the invisibility of God?
The matter remained not fully clear until there emerged the teaching of the Divine Energies, associated with the name of St. Gregory Palamas, the great fourteenth-century Byzantine theologian.
For centuries Eastern Christian monks practiced the transfiguration of their nature similar to the Transfiguration which Jesus Christ manifested on Mount Tabor. Prayers bodies began to emanate a radiation from within, and there was no question but this light was of a divine nature that did not exist in the created world.
The need to evolve a theological explanation for this practice had led St. Gregory Palamas to evolve in detail that inherently biblical creed of the Divine Energies. Rather was he constrained there to due to the emergence of the false allegation as if the light on Mount Tabor was of natural origin similar to the luminous aura of the Hindu yogi.
According to the teaching of St. Gregory Palamas, which the local councils of Constantinople had confirmed, God by His very nature is invisible, undepictable, incomprehensible. Which St. John the Evangelist implies when he says:
"No one has ever seen God" (1:18),
and which is why Moses forbade the representation of God.
However God is alive and operating. Actions, for which the Greek is "energies", of the Holy Trinity is that selfsame divine nature emanating from itself, pouring out. In its quality of energy Divine nature is visible, depictable, comprehensible and, moreover may penetrate from inside and fill human nature.
Hence, we may now understand how God could become visible. Set of the energies of the Holy Trinity forms the eternally uncreated Divine "body" which can be visible to the human eye. In this eternal embodiment of His, the One God is Jesus Christ, He is also Yahweh, He is the Ancient of Days and the One who sits on the throne. In Paradise, Adam saw Him and conversed with Him. And hence, we, employing our erroneous terms, could say that God had revealed Himself to Adam in His "human image". It would be correct though to say that man is created "in the image and likeness" of God, of Jesus Christ in His Divine body.
