First Reading
Jeremiah 20:7-9
O LORD, thou hast deceived me, and I was deceived; thou art stronger than I, and thou hast prevailed. I have become a laughingstock all the day; every one mocks me. For whenever I speak, I cry out, I shout, “Violence and destruction!” For the word of the LORD has become for me a reproach and derision all day long. If I say, “I will not mention him, or speak any more in his name,” there is in my heart as it were a burning fire shut up in my bones, and I am weary with holding it in, and I cannot.

Romans 12:1-2
I appeal to you therefore, brethren, by the mercies of God, to present your bodies as a living sacrifice, holy and acceptable to God, which is your spiritual worship. Do not be conformed to this world but be transformed by the renewal of your mind, that you may prove what is the will of God, what is good and acceptable and perfect.
Gospel
Matthew 16:21-27
From that time Jesus began to show his disciples that he must go to Jerusalem and suffer many things from the elders and chief priests and scribes, and be killed, and on the third day be raised. And Peter took him and began to rebuke him, saying, “God forbid, Lord! This shall never happen to you.” But he turned and said to Peter, “Get behind me, Satan! You are a hindrance to me; for you are not on the side of God, but of men.” Then Jesus told his disciples, “If any man would come after me, let him deny himself and take up his cross and follow me. For whoever would save his life will lose it, and whoever loses his life for my sake will find it. For what will it profit a man, if he gains the whole world and forfeits his life? Or what shall a man give in return for his life? For the Son of man is to come with his angels in the glory of his Father, and then he will repay every man for what he has done.
