Mark 8:27-38
²⁷Jesus went on with his disciples to the villages of Caesarea Philippi; 
     and on the way he asked his disciples, 
          “Who do people say that I am?”  
²⁸And they answered him, 
     “John the Baptist; 
     and others, Elijah; 
     and still others, one of the prophets.”  
²⁹Jesus asked them, 
     “But who do you say that I am?” 
Peter answered him, 
     “You are the Messiah.”  
³⁰And he sternly ordered them not to tell anyone about him.

³¹Then Jesus began to teach them 
     that the Human One must undergo great suffering, 
     and be rejected by the elders, the chief priests, and the scribes, 
     and be killed, 
     and after three days rise again. 
          ³²Jesus said all this quite openly. 
               And Peter took him aside 
               and began to rebuke him. 
          ³³But turning and looking at his disciples, 
               he rebuked Peter and said, 
                    “Get behind me, Satan! 
                         For you are setting your mind 
                              not on divine things but on human things.”

³⁴Jesus called the crowd with his disciples, and said to them, 
     “If any want to become my followers, 
          let them deny themselves 
          and take up their cross and follow me.
               ³⁵For those who want to save their life will lose it, 
               and those who lose their life for my sake, 
                    and for the sake of the gospel, 
                         will save it.
               ³⁶For what will it profit them to gain the whole world 
                    and forfeit their life?
                         ³⁷Indeed, what can they give in return for their life?
     ³⁸Those who are ashamed of me and of my words 
          in this adulterous and sinful generation, 
               of them the Human One will also be ashamed 
                    when he comes in the glory of his Papa with the holy angels.”

Queeries for the text:
Why is Jesus so interested in gossip?
How does Jesus hold saying things quite openly and yet ordering the disciples not to tell anyone?
How do we rebuke Jesus?
What human things are our minds set on?
What divine things are we missing?
What does it mean to deny ourselves and take up our cross?
What is the cost of following Jesus?
What is in profit?
How are we ashamed of Jesus?
