Oftentimes you hear that biblical truth is absolute. This is a core tenet of conservative evangelicalism. The logic behind this belief is based upon a specific perspective on the doctrine of “inspiration”. Conservative evangelicals believe that God directed (through the Holy Spirit) all of the writers of the Old and New Testaments. Since God is absolute truth; and since he is the ultimate author of scripture, it follows that the truth contained therein is absolute.
However, those who oppose this perspective will argue that conservative evangelicals fail to make an important ontological distinction between the object/subject and the relationship they have to truth. They also fail to appreciate the roles communication (more broadly) and language (more specifically) play in the understanding of what is true.
First, the only way to obtain absolute truth is to be the source of that truth. Moreover, if God is absolute truth, then as both subject and object of that truth; he is the only one who has the ability to perceive that truth. Any attempt at ascertaining a truth outside of its foundational sphere always results in something less than its source.
Granted it’s possible that the presupposition regarding the nature of truth is incorrect. Even so, if God is the foundation of the very truth He is asserting; then, the ability to ascertain said truth would elevate the Christian to a divine like being.
It’s important to note that the denial in the absolute nature of scripture does not necessitate that one also deny that God is absolute. In fact, just the opposite is true. Denying the absolute nature of scripture imagines a deity of far greater holiness than one who is epistemically coequal with humanity.
