First Reading Gn 15:5-12, 17-1

God made a covenant with Abraham, his faithful servant.

Taking Abram outside the Lord said, ‘Look up to heaven and count the stars if you can. Such will be your descendants’ he told him. Abram put his faith in the Lord, who counted this as making him justifed. ‘I am the Lord’ he said to him ‘who brought you out of Ur of the Chaldaeans to make you heir to this land.’ ‘My Lord, the Lord’ Abram replied, ‘how am I to know that I shall inherit it?’ He said to him, ‘Get me a three-year-old heifer, a three-year-old goat, a three-year-old ram, a turtledove and a young pigeon.’ He brought him all these, cut them in half and put half on one side and half facing it on the other; but the birds he did not cut in half. Birds of prey came down on the carcasses but Abram drove them off. Now as the sun was setting Abram fell into a deep sleep, and terror seized him. When the sun had set and darkness had fallen, there appeared a smoking furnace and a frebrand that went between the halves. That day the Lord made a Covenant with Abram in these terms: ‘To your descendants I give this land, from the wadi of Egypt to the Great River.’

This is the word of the Lord

Second Reading Phil 3:17-4:1

I preached what they preach, and this is what you believe.

My brothers, be united in following my rule of life. Take as your models everybody who is already doing this and study them as you used to study us. I have told you often, and I repeat it today with tears, there are many who are behaving as the enemies of the cross of Christ. They are destined to be lost. They make foods into their god and they are proudest of something they ought to think shameful; the things they think important are earthly things. For us, our homeland is in heaven, and from heaven comes the saviour we are waiting for, the Lord Jesus Christ, and he will transfgure these wretched bodies of ours into copies of his glorious body. He will do that by the same power with which he can subdue the whole universe. So then, my brothers and dear friends, do not give way but remain faithful in the Lord. I miss you very much, dear friends; you are my joy and my crown.

This is the word of the Lord.

Gospel Lk 9:28-36

As Jesus prayed, the aspect of his face was changed, and his clothing became brilliant as lightning.

Jesus took with him Peter and John and James and went up the mountain to pray. As he prayed, the aspect of his face was changed and his clothing became brilliant as lightning. Suddenly there were two men there talking to him; they were Moses and Elijah appearing in glory, and they were speaking of his passing which he was to accomplish in Jerusalem. Peter and his companions were heavy with sleep, but they kept awake and saw his glory and the two men standing with him. As these were leaving him, Peter said to Jesus, ‘Master, it is wonderful for us to be here; so let us make three tents, one for you, one for Moses and one for Elijah.’ – He did not know what he was saying. As he spoke, a cloud came and covered them with shadow; and when they went into the cloud the disciples were afraid. And a voice came from the cloud saying, ‘This is my Son, the Chosen One. Listen to him.’ And after the voice had spoken, Jesus was found alone. The disciples kept silence and, at that time, told no one what they had seen.
