Yes, that does seem to be Frye's conception. We started off talking about miracles, which seem key to Scriptural history. Such things are counter to the ways of nature. You on the other hand, seem to be asking about how free human action is possible in a world understood naturalistically, in which our bodies obey the unalterable laws of nature.
Hungry lions eat people, unless they are trained otherwise, or frightened of violence.
So my suggestion was that Frye could be helped if he were not to take natural necessity as a given, but were willing to take seriously the idea that the laws of science result from what he calls descriptive writing, which is human creation, just like the other kinds of writing that he discusses. But perhaps to go this far, at least up until very recently, would be dangerous to one's academic credentials.
