Genesis 17: 1-7, 15-16

The Covenant with Abram

17 When Abram was ninety-nine years old, the Lord appeared to him and said, “I am God Almighty[a]; walk before me faithfully and be blameless. 2 Then I will make my covenant between me and you and will greatly increase your numbers.”

3 Abram fell facedown, and God said to him, 4 “As for me, this is my covenant with you: You will be the father of many nations. 5 No longer will you be called Abram[b]; your name will be Abraham,[c] for I have made you a father of many nations. 6 I will make you very fruitful; I will make nations of you, and kings will come from you. 7 I will establish my covenant as an everlasting covenant between me and you and your descendants after you for the generations to come, to be your God and the God of your descendants after you.

15 God also said to Abraham, “As for Sarai your wife, you are no longer to call her Sarai; her name will be Sarah. 16 I will bless her and will surely give you a son by her. I will bless her so that she will be the mother of nations; kings of peoples will come from her.”

Mark 8: 31-38

Jesus predicts his death

31 He then began to teach them that the Son of Man must suffer many things and be rejected by the elders, the chief priests and the teachers of the law, and that he must be killed and after three days rise again. 32 He spoke plainly about this, and Peter took him aside and began to rebuke him.33 But when Jesus turned and looked at his disciples, he rebuked Peter. “Get behind me, Satan!” he said. “You do not have in mind the concerns of God, but merely human concerns.”

The Way of the Cross

34 Then he called the crowd to him along with his disciples and said: “Whoever wants to be my disciple must deny themselves and take up their cross and follow me. 35 For whoever wants to save their life[a] will lose it, but whoever loses their life for me and for the gospel will save it.36 What good is it for someone to gain the whole world, yet forfeit their soul? 37 Or what can anyone give in exchange for their soul? 38 If anyone is ashamed of me and my words in this adulterous and sinful generation, the Son of Man will be ashamed of them when he comes in his Father’s glory with the holy angels.”
