Letter to the Hebrews 11,1-7.
Brothers and sisters: Faith is the realization of what is hoped for and evidence of things not seen.
Because of it the ancients were well attested.
By faith we understand that the universe was ordered by the word of God, so that what is visible came into being through the invisible.
By faith Abel offered to God a sacrifice greater than Cain's. Through this he was attested to be righteous, God bearing witness to his gifts, and through this, though dead, he still speaks.
By faith Enoch was taken up so that he should not see death, and "he was found no more because God had taken him." Before he was taken up, he was attested to have pleased God.
But without faith it is impossible to please him, for anyone who approaches God must believe that he exists and that he rewards those who seek him.
By faith Noah, warned about what was not yet seen, with reverence built an ark for the salvation of his household. Through this he condemned the world and inherited the righteousness that comes through faith.
Holy Gospel of Jesus Christ according to Saint Mark 9,2-13.
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."
