In a most fascinating study by Jamin Hübner, called “The Evolution of Complementarian Exegesis,” Priscilla Papers 29 (2015) 11-13, we are treated to specific examples of complementarians (=hierarchicalists, =patriarchalists) shifting their views on points of exegesis. The changes are the result of further study but the conclusion Hübner draws is that complementarians have not had as stable an exegesis as many think.

 We have concluded that… 1 Timothy 2:12 is intended to eliminate women from the office of elder (that is, women cannot occupy the official teaching-ruling office of the church).”
 Possibly Paul aims to disqualify women from the office of elder before he defines the requirements of that office [in 1 Tim 3],” and “It is debatable whether this passage specifically excludes women from the office of elder or not.”
 It is difficult to avoid the conclusion that Paul cites Eve’s failure as exemplary and perhaps causative of the nature of women in general and that this susceptibility to deception bars them from engaging n public teaching..
 It may be that Paul wants to imply that all women are, like Eve, more susceptible to being deceived than are men, and that this is why they should not be teaching men! While this interpretation is not impossible, we think it unlikely.
 Appointing women to the teaching office is prohibited because they are less likely to draw a line on doctrinal non-negotiables, and thus deception ind false teaching will more easily enter the church.
 He states of his former view, “it seems that this view also strays from the text, even if one agrees that such differences exist between men and women. If Paul argued that women were deceived because of innate dispositions, the goodness of God’s creative work is called into question.”
 He gave three arguments to show that the term “head” (kephale) in 1 Cor 11:2-16 means “authority” and not “source.” In his 2005 essay in Two Views on Women in Ministry, however, he opened up to the possibility “that kephale in some contexts denotes both ‘authority over’ and ‘source.’
 “Whenever we have seen this verb [authente0] occur, it takes a neutral sense, ‘have authority’ of exercise authority,’ with no negative connotation attaching to the word itself.”
 … his position changed so that the term “is primarily positive or neutral.”
So Hübner concludes:
One obvious implication is that complementarians should be careful in proclaiming to possess a sure foundation that evidently does not exist. As long as interpretations keep changing in substantial ways, interpreters ought to exercise all the more caution about wielding such interpretations to prohibit women from proclaiming the gospel to men.
