All that is truthful, from whatever source, is unified, and will cohere with whatever else is truthful. (“Because God’s reality is unified and coherent, centered as it is on the person of Christ, all truthful apprehensions of that reality, or truthful expressions of those apprehensions, will cohere and contribute to an integrated, unified, Christ-centered vision of all things.”

Duane Litfin writes that the slogan “All truth is God’s truth” became popular because it “encapsulated a set of convictions that are vital for the Christian’s intellectual task. These ideas lie embedded in the sloan as entailments, necessary implications. To embrace the slogan was to embrace these implications. My purpose here is to surface these entailments so that, even if we may allow an overworked catchphrase to rest in peace, we will not lose the truths it was designed to express.”

Here is his outline:

1. God exists. (“This is the most basic idea of all. It is the foundation for all that a Christian can know.”)
2. Through the agency of his Son, God created the universe and all that is in it.
3. We can therefore entertain an intellectual construct called “reality.” (Reality = “things as God knows them to  be.” “While a God-centered definition of reality does not by itself grant usaccess to that reality . . . it is nonetheless what makes it possible to talk about reality in the first place.”)
4. This reality is complex and multi-dimensional. (“The cosmos God created . . . has physical, spiritual, and moral dimensions to it, but each dimension is fully real because its reality is anchored in the fact that it is part of what God knows to be the case.”)
