Blessed are the pure in heart, for they shall see God.
Jesus the incarnate God reveals to us the hidden mystery of God, and yet in that revelation there is hidden a mystery. We see in Christ both God and the image (icon) of God, but this very revelation reveals that God is more mysterious than we imagine. God whose creation is by definition “not God” becomes “not God”; in so doing He makes that which is “not God” to become God. “God became man so that man might become God,” said St. Athanasius.
He who has seen me has seen the Father... (John 14:9)
The incarnation opened our eyes to what God had previously hidden from us.
“In the present world, the glory of God is seen only by a select few, but ‘in the time to come’ all will see it, as it says in Isa 40:5, ‘The glory of the Lord shall be revealed, and all flesh shall see it together’. cf. Lev. Rab. 1:14. (Craig A. Evans, Hearing the Old Testament in the New Testament, pg. 100)
In Christ that glory of God is revealed to all. Isaiah’s “time to come” has come to pass.
And the Word became flesh and dwelt among us, full of grace and truth; we have beheld his glory, glory as of the only Son from the Father. (John 1:14)
The Gospel Lesson of the man born blind who is given his sight (John 9) is most amazing because the man not only receives physical sight, he also sees God.
So they again said to the blind man, “What do you say about him, since he has opened your eyes?” He said, “He is a prophet.” The Jews did not believe that he had been blind and had received his sight, until they called the parents of the man who had received his sight, and asked them, “Is this your son, who you say was born blind? How then does he now see?” His parents answered, “We know that this is our son, and that he was born blind; but how he now sees we do not know, nor do we know who opened his eyes. Ask him; he is of age, he will speak for himself.” His parents said this because they feared the Jews, for the Jews had already agreed that if any one should confess him to be Christ, he was to be put out of the synagogue. Therefore his parents said, “He is of age, ask him.”
So for the second time they called the man who had been blind, and said to him, “Give God the praise; we know that this man is a sinner.” He answered, “Whether he is a sinner, I do not know; one thing I know, that though I was blind, now I see.” They said to him, “What did he do to you? How did he open your eyes?” He answered them, “I have told you already, and you would not listen. Why do you want to hear it again? Do you too want to become his disciples?” And they reviled him, saying, “You are his disciple, but we are disciples of Moses. We know that God has spoken to Moses, but as for this man, we do not know where he comes from.” The man answered, “Why, this is a marvel! You do not know where he comes from, and yet he opened my eyes. We know that God does not listen to sinners, but if any one is a worshiper of God and does his will, God listens to him. Never since the world began has it been heard that any one opened the eyes of a man born blind. If this man were not from God, he could do nothing.” They answered him, “You were born in utter sin, and would you teach us?” And they cast him out. Jesus heard that they had cast him out, and having found him he said, “Do you believe in the Son of man?” He answered, “And who is he, sir, that I may believe in him?” Jesus said to him, “You have seen him, and it is he who speaks to you.” He said, “Lord, I believe”; and he worshiped him.
