I find this interesting to learn. I learned that the authority a person hears through nature is the same voice of authority revealed in supernatural commands. Part of this is that a person's conscience is revelational. Even if we compromise, our conscience remains revelational, I think, because it shows our fallen condition and our need for God.

But I have a question, I didn't really know if my interpretation here was right.

The second thing that Van Til identified in his discussion of the authority of natural theology is the inclusion of what Francis Schaeffer describes as the "mannishness" of man in addition to man's environment. By this term, I understand anything that makes man a man. In the language of Van Til, man's "constitution as a covenant personality" (ibid.).

"Mannishness" does it pertain to the authoritative character of man?
