Genesis 22:1-2, 9a, 10-13, 15-18

1After these things occurred, God tested Abraham, and he said to him, “Abraham, Abraham.” And he answered, “Here I am.” 2He said to him: “Take your only begotten son Isaac, whom you love, and go into the land of vision. And there you shall offer him as a holocaust upon one of the mountains, which I will show to you.” 3And so Abraham, getting up in the night, harnessed his donkey, taking with him two youths, and his son Isaac. And when he had cut wood for the holocaust, he traveled toward the place, as God had instructed him. 4Then, on the third day, lifting up his eyes, he saw the place at a distance. 5And he said to his servants: “Wait here with the donkey. I and the boy will hurry further ahead to that place. After we have worshipped, will return to you.” 6He also took the wood for the holocaust, and he imposed it upon his son Isaac. And he himself carried in his hands fire and a sword. And as the two continued on together, 7Isaac said to his father, “My father.” And he answered, “What do you want, son?” “Behold,” he said, “fire and wood. Where is the victim for the holocaust?” 8But Abraham said, “God himself will provide the victim for the holocaust, my son.” Thus they continued on together. 9And they came to the place that God had shown to him. There he built an altar, and he set the wood in order upon it. And when he had bound his son Isaac, he laid him on the altar upon the pile of wood. 10And he reached out his hand and took hold of the sword, in order to sacrifice his son. 11And behold, an Angel of the Lord called out from heaven, saying, “Abraham, Abraham.” And he answered, “Here I am.” 12And he said to him, “Do not extend your hand over the boy, and do not do anything to him. Now I know that you fear God, since you have not spared your only begotten son for my sake.” 13Abraham lifted up his eyes, and he saw behind his back a ram among the thorns, caught by the horns, which he took and offered as a holocaust, instead of his son. 14And he called the name of that place: ‘The Lord Sees.’ Thus, even to this day, it is said: ‘On the mountain, the Lord will see.’ 15Then the Angel of the Lord called out to Abraham a second time from heaven, saying: 16“By my own self, I have sworn, says the Lord. Because you have done this thing, and have not spared your only begotten son for my sake, 17I will bless you, and I will multiply your offspring like the stars of heaven, and like the sand which is on the seashore. Your offspring will possess the gates of their enemies. 18And in your offspring, all the nations of the earth will be blessed, because you obeyed my voice.”

Romans 8:31b-34

34who is the one who condemns? Christ Jesus who has died, and who has indeed also risen again, is at the right hand of God, and even now he intercedes for us.
Gospel

Mark 9:2-10

2And his vestments became radiant and exceedingly white like snow, with such a brilliance as no fuller on earth is able to achieve. 3And there appeared to them Elijah with Moses; and they were speaking with Jesus. 4And in response, Peter said to Jesus: “Master, it is good for us to be here. And so let us make three tabernacles, one for you, and one for Moses, and one for Elijah.” 5For he did not know what he was saying. For they were overwhelmed by fear. 6And there was a cloud overshadowing them. And a voice came from the cloud, saying: “This is my most beloved Son. Listen to him.” 7And immediately, looking around, they no longer saw anyone, except Jesus alone with them. 8And as they were descending from the mountain, he instructed them not to relate to anyone what they had seen, until after the Son of man will have risen again from the dead. 9And they kept the word to themselves, arguing about what “after he will have risen from the dead” might mean. 10And they questioned him, saying: “Then why do the Pharisees and the scribes say that Elijah must arrive first?”
