Who do people say that I am?

Reading 1 GN 9and1-13 God blessed Noah and his sons and said to themand Be fertile and multiply and fill the earth.Dread fear of you shall come upon all the animals of the earthand all the birds of the air,upon all the creatures that move about on the groundand all the fishes of the seainto your power they are delivered.Every creature that is alive shall be yours to eatI give them all to you as I did the green plants.Only flesh with its lifeblood still in it you shall not eat.For your own lifeblood, too, I will demand an accountingandfrom every animal I will demand it,and from one man in regard to his fellow manI will demand an accounting for human life.If anyone sheds the blood of man,by man shall his blood be shedFor in the image of Godhas man been made.Be fertile, then, and multiplyabound on earth and subdue it. God said to Noah and to his sons with himand See, I am now establishing my covenant with youand your descendants after youand with every living creature that was with youandall the birds, and the various tame and wild animalsthat were with you and came out of the ark.I will establish my covenant with you,that never again shall all bodily creatures be destroyedby the waters of a floodthere shall not be another flood to devastate the earth. God addedand This is the sign that I am giving for all ages to come,of the covenant between me and youand every living creature with youandI set my bow in the clouds to serve as a signof the covenant between me and the earth.

Gospel MK 8:27-33 Jesus and his disciples set outfor the villages of Caesarea Philippi.Along the way he asked his disciples, Who do people say that I am? They said in reply, John the Baptist, others Elijah,still others one of the prophets. And he asked them, But who do you say that I am? Peter said to him in reply, You are the Christ. Then he warned them not to tell anyone about him.He began to teach themthat the Son of Man must suffer greatlyand be rejected by the elders, the chief priests, and the scribes,and be killed, and rise after three days.He spoke this openly.Then Peter took him aside and began to rebuke him.At this he turned around and, looking at his disciples,rebuked Peter and said, Get behind me, Satan.You are thinking not as God does, but as human beings do.
