A Priori

There is no point arguing with someone who believes that The Bible is a priori non-falsifiable.

That's true of anything. If someone has decided to believe something is non-falsifiable, then no amount of logical argumentation will make a difference.

Incidentally, this is where the "science" of climate change has come. Quotes like "the matter is settled ... it is now merely a question of what we do about it" float around like confetti. Of course the science is not at all settled:

• That the earth has warmed over the last century may be true enough.
• Whether the change is anything abnormal within the context of normal historical cycles is almost never discussed
• Whether the change is in fact due to human activity is a wide open question, despite "scientists" hoping desperately to make it a settled matter.
• Whether any proposed method of correction will actually do anything is an even more wide open question.

You and I will need to simply agree to disagree on the Bible. I don't claim to have perfect faith in its infallibility. I do claim to understand that unless I believe it is essentially true, then I really have no basis to believe that any one part of it is true. John 3:16 becomes just another component that may or may not hold validity.
