Here is an excellent excerpt from “Discovering Biblical Equality, Complementarity without Hierarchy”. Amazon carries it HERE. In chapter 18, “Equal in Being, Unequal in Role”, Groothuis points out that one cannot be inherently equal and at the same time inherently unequal. Groothuis notes that Aristotle held the view that women were inferior and that this view continued until very recently.
Kruse notes: on his Blog
“Groothuis raises the question of whether it is logically possible for a person to be ontologically equal but permanently subordinate. She aims to show the illogic of this “equal/unequal” formulation.”
“I believe we can choose between the two biblical interpretations by assessing each one in light of two fundamental premises. The first premise is theological: according to Scripture, women and men are equal spiritually and ontologically – a point that is uncontested in the gender debate. The second premise is logical: the foundational and indisputable law of noncontradiction, which states that A and non-A cannot both be true at the same time in the same respect. The law of non-contradiction is not a mere human construct that God’s truth somehow transcends. … it is axiomatic that if the Bible contradicts itself, then it cannot be true in all that it affirms. (304)”
Groothuis writes that:
“Either (1) women are created by God for perpetual subordination to men and so are not equal to men in their nature/being/essence, or (2) women are created equal with men and so cannot be permanently, comprehensively and necessarily subordinate to men. (305)”
