You're naïve if you think Christians can't be naïve!

Paul had taught the Thessalonians about Christ's coming, and there remained a need for more teaching, since some had misrepresented Christ's coming. Simple. Where's your wisdom, Old Sage?
Jesus himself warned his Disciples that this kind of deception would follow his ministry. Was Jesus naive even after he had taught his Disciples, failing to explore every element of that deception? No, he equipped Paul, through the Holy Spirit, to deal with it when it came.
See above. Not everything is covered in the 1st go around. Sometimes we have to deal with things as they come up. Then we can look back and realize we'd been warned. Sometimes we need help with that warning! It seems you still don't get the reason for the warning about "False Christs?"
Aren't you being a little over dramatic here? I never called this a crisis of great proportion! It was simply a problem the Church needed to deal with, such as we need to deal with Jehovah's Witnesses today. Nobody is having a heart attack over their existence. They simply need to be exposed as imposters.
The fact we have confidence in having eternal life does not free us from problems in the present life. We have obligations to be on the alert. So said Jesus, right? Just because we're saved doesn't mean that Christians don't make bonehead mistakes, such as I made when I got into a Christian cult in S. CA many years ago. I had to extract myself, and went through some mind-bending changes. Deception is indeed a heavy mental thing--it is a spiritual bondage.
But as I said, I don't necessarily see the application of Jesus' Coming in this cult the same way it *should* be seen. They may have viewed the very existence of their cult as evidence that they were, in some strange sense, Jesus' Coming.
Is this really so unbelievable? We have had groups all through history claiming to be in some sense the coming of the Kingdom, or predictors of the imminent coming of the Kingdom. Even today we have religious cults that claim to be God's Kingdom either already here on earth or coming to be on earth through them.
I suppose I just have more experience with the cults than you do? I've seen them up close, and have actually been *in them.*
It seems my demise has been grossly misrepresented.

It happens....
You're entitled to your opinion. I hope you've convinced yourself my view is "dead?" Then you won't have to respond to it anymore!
