A man can no more diminish God's glory by refusing to worship Him than a lunatic can put out the sun by scribbling the word, 'darkness' on the walls of his cell.
C. S. Lewis
Gospel text (Mk 9:2-13): Jesus took with him Peter and James and John, and led them up a high mountain. There his appearance was changed before their eyes. Even his clothes shone, becoming as white as no bleach of this world could make them. Elijah and Moses appeared to them; the two were talking with Jesus.
Then Peter spoke and said to Jesus, «Master, it is good that we are here; let us make three tents, one for you, one for Moses and one for Elijah». For he did not know what to say; they were overcome with awe. But a cloud formed, covering them in a shadow, and from the cloud came this word, «This is my Son, the Beloved; listen to him». And suddenly, as they looked around, they no longer saw anyone except Jesus with them.
As they came down the mountain, He ordered them to tell no one what they had seen, until the Son of Man be risen from the dead. So they kept this to themselves, although they discussed with one another what ‘to rise from the dead’ could mean.
Finally they asked him, «Why then do the teachers of the Law say that Elijah must come first?». Jesus answered them, «Of course, Elijah will come first so that everything may be as it should be... But, why do the Scriptures say that the Son of Man must suffer many things and be despised? I tell you that Elijah has already come and they have treated him as they pleased, as the Scriptures say of him».
Everybody instinctively longs for happiness. But often one does not know what happiness is, and searches in places where there is no happiness and where it cannot be. By His Transfiguration on Mount Tabor Lord Jesus Christ demonstrated that real happiness lies in union with God. In such union the entire essence of a human changes, or transfigures: unspeakable peace, harmony and joy settle in the soul; the intellect receives enlightenment, and all abilities of a person reach their utmost extent; the soul fills with Divine light and becomes godlike. Now the Kingdom of God enters the human.
For humans not to fall to laziness and pride, it is not given to them to feel the entire joy of communion with God, which shall be the reward in the world to come. Still at times our Lord out of His Grace gives us to feel this special joy of communion with Him. Such communion is perceived as shining of a mysterious light inside a person. This shining brings forward the particular unforgettable bliss, inexplicable to those who have never experienced it. Compared to it, all worldly joys seem scanty and miserable. We believe that the eternal life will start after this temporary world, and 'Then shall the righteous shine forth as the sun in the kingdom of their Father' (Matt 13:43).
The Transfiguration is just a moment, a taste of glory, to give the apostles the possibility to decipher the meaning of that intimate moment.
Jesus had announced his disciples the imminent moment of His Passion, but upon seeing them so perturbed because of his tragic final, He explains with words and facts how his last days would be: days of passion and death, but days that will be over with his resurrection. Here is the enigma unraveled. Saint Thomas Aquinas says: «To properly walk one's way it takes one to know first, somehow, the target one is aiming at».
In the same way, today let us be challenged to strive to praise God, no matter how visible he is in our lives. At times we will experience a divine intervention, or a miracle: some clear indication that he is evident and present. Yet, there will be times when we feel like we are alone in our lives; faith will require us to step out of our comfort zone and to accept that God loves us and that He is there, even when we don’t want to believe it.
