Warfield is a bit dated. Don’t you think? Consider the source.
Evidence now shows that the Old Testament canon was not closed even among the Jews at the time the New Testament was written and that the Deuterocanonical books had influences on numerous passages.
And if you look at the Bible that was brought to Ethiopia in the 4th century, it shows a remarkably different canon. http://ethiopianorthodox.org/english/canonical/books.html
And as far as the Epistles of St. Ignatius are concerned, the ones I’ve cited are regarded by scholars as having been authentic.
The differences between the longer and shorter recensions are not unlike the different manuscript recensions we find among the early Biblical manuscripts.
That is they use different words to say just about the same thing. You can’t avoid copyist error.
Take the ending of Mark’s gospel for example, it doesn’t exist in some early manuscripts.

As dated as St. Ignatius?
You can't be serious in that criticism......
