For Romanides, the full Biblical weight of the cure of illumination and glorification is found in the high- priestly prayer of Jesus in John 17.   Here, Christ is not praying for divided churches, but rather for the unity of his disciples, (and their followers to come,) in the cure of glorification.  What many Christians and Biblical scholars do not know, is that an Old and New Testament word for theosis, (usually translated divinization,) is glorification.  Romanides offers five keys to Biblical interpretation:

1) Humanity and its institutions, including all its religions, is sick, and there is only one explicit and precise cure for the sickness: "There is no God except Yahweh."

2) There is only the Uncreated, (the Creator), and the created, ( the world and its creatures).  There is a precise demarcation of Biblical terms between those referring to that which is uncreated and that which is created.

3) There is absolutely no similarity between the Creator, the uncreated, and that which He has brought into being, the created. "It is impossible to express God and even more impossible to conceive Him."  Biblical terms, expressions, and histories are not meant to communicate to us concepts and ideas about God, but to guide us to purify our hearts, and then lead us forward to the illumination of our hearts, and finally on to glorification. 

4)  The basic cause of the sickness of the human soul is a "short-circuit" between the brain and the heart, a result of which the imagination is distorted, fantasies and illusions arise, and contact with spiritual reality, the only true reality, is lost. What is sick in the heart is its noetic faculty (which early Christian tradition calls the nous, or the eye of the soul).  This noetic faculty is not the intellectual faculty which is centred in the brain.  When the soul is cured, the brain and intellect go about their normal work while the nous prays unceasingly in the heart.  The cure of the sickness of the human soul and religions is always, from the beginning to the end stages of the cure, "the transformation of selfish happiness-seeking love into the selfless love of one's own crucifixion, which is glorification."  This crucifixion/glorification is what both the OT prophets and the NT apostles experienced and wrote about.

5) Biblical expressions about God are not abstract concepts but practical means of guidance toward purification and illumination.  Glorification, a gift or grace bestowed by the Pre-Incarnate and Incarnate Lord (Yahweh) of Glory "is to see Him by means of His uncreated glory or rule." The frequently used expression "Kingdom of God" is a mistranslation.  The NT Greek word, translated by the English word "kingdom," means really "the rule or reign" of God. It refers to the reality of coming under God's authority.
