Here are some of Edward Adams’ thoughts on narrative criticism:

First, it should be practically useful for this investigation [of Paul’s story of God and Creation]. If it is going to serve as a genuinely helpful descriptive tool, it must be neither too general or bland to be of discriminatory use nor too specific to be applicable to forms of discourse other than those that are most obviously narrative (e.g. fairy tales comic strips, conventional novels, gospels).

Second, it should not be an arbitrary definition, formulated just to suit the particular needs of this exercise. Rather, it should be soundly based in established narrative theory.

Third, it should resonate with our general experience and expectations of narrative. It ought to be sufficiently intuitive to gain a measure of common assent.
