This is my beloved Son

Holy Gospel of Jesus Christ according to Saint Mark 9:2-13.
After six days Jesus took Peter, James, and John and led them up a high mountain apart by themselves. And he was transfigured before them,
and his clothes became dazzling white, such as no fuller on earth could bleach them.
Then Elijah appeared to them along with Moses, and they were conversing with Jesus.
Then Peter said to Jesus in reply, "Rabbi, it is good that we are here! Let us make three tents: one for you, one for Moses, and one for Elijah."
He hardly knew what to say, they were so terrified.
Then a cloud came, casting a shadow over them; then from the cloud came a voice, "This is my beloved Son. Listen to him."
Suddenly, looking around, they no longer saw anyone but Jesus alone with them.
As they were coming down from the mountain, he charged them not to relate what they had seen to anyone, except when the Son of Man had risen from the dead.
So they kept the matter to themselves, questioning what rising from the dead meant.
Then they asked him, "Why do the scribes say that Elijah must come first?"
He told them, "Elijah will indeed come first and restore all things, yet how is it written regarding the Son of Man that he must suffer greatly and be treated with contempt?
But I tell you that Elijah has come and they did to him whatever they pleased, as it is written of him."


Commentary of the day : An anonymous Syrian writer
« This is my beloved Son»

Jesus led Peter, James and John up the mountain and showed them his divine glory even before the resurrection. So that, when he rose from the dead in the glory of his divine nature, they would recognize that he hadn't received this glory as a reward for his suffering, as though he had need of it, but that it belonged to him before the ages began at his Father's side and with the Father. This is what he himself said as his freely accepted Passion drew near: «Glory me, Father, with you, with the glory that I had with you before the world began» (Jn 17,5). It was this glory of his divinity, mysteriously enclosed within his humanity, that he showed his disciples on the mountain. And these... saw two suns: one shining in the sky as usual and another that shone in an unaccustomed way; one casting light on the world from high in the firmament and another radiant for them alone in the countenance turned towards them...

Then Moses and Elijah appeared... and thanked him that their words, as those of all the other prophets, had been fulfilled by his coming. They offered him worship for the salvation he would accomplish for the sake of the whole world and for the fulfilment of the mystery they had been entrusted to foretell. Thus both apostles and prophets were filled with joy on that mountain. The prophets rejoiced to see his humanity, which they had not been able to know beforehand; the apostles rejoiced to see the glory of his divinity, which they had not yet known about, and hear the Father's voice bear witness to his Son. By it, and by the glory of his divinity shining from his body, they learned about his incarnation, which up to then had remained unknown to them.
