1 John 4:1 compared to The No True Scotsman Fallacy and sophisms

[ignoramus]

Just saying, "someone isn't a Christian," isn't exactly committing the NTS fallacy though, Thomas.  It's used in refutation to evidence supporting an argument.  You are going to have to give me a more specific example than what you just presented.

LadyForCamus,

I was testing you.  Maybe you've learnt something new from it.  I don't do it with bad will.

To help, you may think of a Christian saying that another person called a Christian, is not Christian and an atheist thinking they can use The No True Scotsman Fallacy to show how it's wrong of a Christian to say such things.

 I love this stuff! I think you need to get your lawyers to talk to our lawyers to nut out the finer technicalities of the fallacy before we can speak further.
You know, everything in the world comes down to technicalities in the end.
Unfortunately, your prime witness is nowhere to be found!
