Truth Revealed to Us - What the New Testament Says

A timely conversation with a young protestant apologist ended with this odd claim by him: "The scripture alone reveals the truth. Let it speak alone." The oddity of this claim coming from someone espousing sola scriptura is two fold. First, scripture never makes any such claim. Second, the New Testament points to three different sources of the revelation of truth to mankind. One of them ends today with the Ascension of Christ but opens the door to the coming of the second. And the final revelation of truth is here for us even to the present day.
