[quote found on The Heresy]

The error of textualism is not doctrinal. It is more subtle than that and much more difficult to discover, but its effects are just as deadly. Not its theological beliefs are at fault, but its assumptions.
It assumes, for instance, that if we have the word for a thing we have the thing itself. If it is in the Bible, is is in us. If we have the doctrine, we have the experience. If something was true of Paul it is of necessity true of us because we accept Paul’s epistles as divinely inspired. The Bible tells us how to be saved, but textualism goes on to make it tell us that we are saved, something which in the very nature of things it cannot do. Assurance of individual salvation is thus no more than a logical conclusion drawn from doctrinal premises, and the resultant experience wholly mental.

Then came the revolt. The human mind can endure textualism just so long before it seeks a way of escape. - A.Z. Tozer [noted in this post]
