Don't start with that one, please! You'll be Marked™ or worse faster than you can possibly imagine.
Try something that the Elder™ isn't prepared for, and won't be able to answer.
Like this:
C: "I'm having a hard time understanding why everyone hates Judas so much."
E: "Well, he betrayed Jesus, duh!"
C: "Yes, I get *that*, but nobody seems to get that the betrayal was essential in order for prophecies to be fulfilled about Jesus. If *nobody* had betrayed Jesus, he would never have been able to fulfill the prophecy, become The Lamb of God, and a sacrifice to atone for our sins."
E: "Well he was just a bad guy."
C: "Was he *really* though?? Or is he just a scapegoat for people to hate? Aren't prophecies like puzzles? All the pieces are necessary in order to complete the picture. Without Judas, Jesus would have just been some smart Jewish guy who was really popular with the people. Those people were willing to hide Jesus and help him escape from the soldiers who were searching for him, who knows if he ever would have been found another way other than by being betrayed?"
E: "Well, this has been a great chat. I have to run, my wife wants me to pick up milk on the way home."
C: (to himself) BOOOOM! (mic drop)
I had similiar thoughts not many weeks ago, but the case is that the Elder made me send him a question so that he could prepare. I wont be able to backtrack now, so my choices are either to go hardmode and enter a discussion, or backtrack and be a good sheep and conform. Your advice is good, but in my inexperince i have put mysef in a corner, sadly. I wont act the same way another time, that is for sure.
