In the past, we had comments on a post that mentioned Second Isaiah criticism of the Book of Mormon.

That criticism known as the Second Isaiah criticism is that since the parts of Isaiah in the Book of Mormon come from the parts of Isaiah identified as “Second Isaiah,” the Book of Mormon is false. This is because Second Isaiah must have been written too late to be part of a legitimate Book of Mormon.

Isaiah

The criticism all depends on the dating theory or thesis for those portions. That is usually not explained. So I am explaining it here.

In short, the dating theory for “Second Isaiah” has the following parts:

  • There is no God.
  • Therefore there is no prophecy.
  • The areas of Isaiah linked stylistically together (because they address the future) must therefore have originated after the events prophesied came to pass.

Most people discussing it kind of leave off the premises and cut to the end.

But that is the core of the argument.

Now there is an identifiable part of Isaiah written in what is referred to as a more mature style. (And yes, I know word map studies do not support the claim). Historically in works such as the Dead Sea Scrolls that did not include other parts of Isaiah, what is referred to as second Isaiah was included.

The discussion on how to identify Second Isaiah as distinct from Isaiah is a distraction from this analysis other than it is applied to parts otherwise requiring the ability to have foreseen the future.

The Cliff Notes summary of Second Isaiah—this link discusses the theory at length.

It is significant that the style analysis is interesting but does not create the dating. The dating theory currently used has the very simple antecedents set out above. That is, it is based on prophecy being impossible because there is no God.

Is the argument that the Book of Mormon is false because there is no God persuasive? I think the fact that those who use the Second Isaiah argument leave the premise out speaks for itself.

I will also note that since Christ quotes from Second Isaiah several times and attributes the citations to Isaiah the argument is also used to deny Christ.

That has been similarly not persuasive.
