Nothing inherently wrong in this quote.


"Divine revelation is the source of all truth,

This seems pretty basic to me. It's implied in the WCF chapter 1, and that "God is true" and all truth flows from God. Man is not autonomous but depends on God for all things.


the truth of Christianity included;

Clearly we could not know the Gospel if not for God's revelation.


reason is the instrument for recognizing it;

This is basic to being rational thinking people. You recognize truth by using reason. Right thinking is required to differentiate fact from fiction. But reason is not truth, but a tool for separating truth from false ideas.


Scripture is its verifying principle;

If nothing else, we know the Scriptures are true and inerrant. Thus we can confirm which ideas are true if they are from Scripture; or if they are reasonable opinion if they do not contradict Scripture. Anything contradicting Scripture is false.


logical consistency of a negative test for truth and coherence a subordinate test.

Again this has to do with right thinking and the fundamentals of logic and reason. Starting with the truth of Scripture as a fundamental principle we can test ideas to see if they are coherent with Scripture, or implied by Scripture.


The task of Christian theology is to exhibit the content of biblical revelation as an orderly whole."

Systematic Theology 101. And Apologetics 101. If your worldview in incoherent, it falls apart. There's no point in holding Christianity up as the truth if our theology is full of contradictions.

I don't know if Carl Henry would say Al Mohler's summation was spot on, but if it is, I think it's pretty basic stuff. And note he is speaking of Henry's apologetics specifically.
