The Reformed Tradition has long referred to Genesis 1:28 as the “Cultural Mandate” (cf. Francis Shaefer and Abraham Kuyper). Culture, defined by Ken Myers, is “what human beings make of the world – in both senses” — as humans create and interpret they are making culture.
This “cultural mandate” is given it’s shape in Genesis through two hendiadys (that is, two words working together to infer one meaning – two through one): First, “fruitful and multiply” and second, “subdue and dominion”.
