Here is a passage said to be a quote from Gamaliel's speech to the Sanhedrin regarding John and Peter:
But a Pharisee in the Sanhedrin named Gamaliel, a teacher of the law, respected by all the people, stood up, ordered the men to be put outside for a short time, and said to them, “Fellow Israelites, be careful what you are about to do to these men. Some time ago, Theudas appeared, claiming to be someone important, and about four hundred men joined him, but he was killed, and all those who were loyal to him were disbanded and came to nothing. After him came Judas the Galilean at the time of the census. He also drew people after him, but he too perished and all who were loyal to him were scattered. So now I tell you, have nothing to do with these men, and let them go. For if this endeavor or this activity is of human origin, it will destroy itself. But if it comes from God, you will not be able to destroy them; you may even find yourselves fighting against God.” They were persuaded by him.*
Also, from today's readings we have this little gem:
“Get behind me, Satan! For you are setting your mind not on divine things but on human things.”
I think that most of the time my own mind is set on human things. I wonder if Jesus has softened his tone on that any?
