Because they've never let me down and the words speak the truth.

[Campion]

You know that the books in your bible are the books that belong there because they've never let you down and they speak the truth?

IOW, it's entirely subjective, the way Mormons talk of a "burning in the bosom" when they read the BoM.

What, exactly, has "never let you down" in the Epistle to Philemon? 2 John?

Historically speaking, how was the decision made as to what books belonged in the NT, and by whom was that decision made, and when?

The books of the Bible removed in the 16th century by the "reformers" also speak the truth, even though they contradict the human traditions of the Protestant Reformation.
