Gospel text (Mark 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»
