Mark 8:29-38

29 Then he saith to them: But whom do you say that I am? Peter answering said to him: Thou art the Christ.

30 And he strictly charged them that they should not tell any man of him.

31 And he began to teach them that the Son of man must suffer many things and be rejected by the ancients and by the high priests and the scribes: and be killed and after three days rise again.

32 And he spoke the word openly. And Peter taking him began to rebuke him.

33 Who turning about and seeing his disciples, threatened Peter, saying: Go behind me, Satan, because thou savourest not the things that are of God but that are of men.

34 And calling the multitude together with his disciples, he said to them: If any man will follow me, let him deny himself and take up his cross and follow me.

35 For whosoever will save his life shall lose it: and whosoever shall lose his life for my sake and the gospel shall save it.

36 For what shall it profit a man, if he gain the whole world and suffer the loss of his soul?

37 Or what shall a man give in exchange for his soul:

38 For he that shall be ashamed of me and of my words, in this adulterous and sinful generation: the Son of man also will be ashamed of him, when he shall come in the glory of his Father with the holy angels.
