Both Biblical and Egalitarian

Rebecca Groothius recently blogged that one can be a Christian egalitarian without following the politics of feminism. In her first major point she writes:

Biblical equality is not equivalent to the politics of feminism (the incessant rhetoric of patriarichal-complementarians not withstanding). Rather, biblical equality seeks to understand and explicate biblical teaching regarding the mission and meaning of women and men in the family of God. The question specifically at issue is whether or not the believer’s authority in Christ is conditioned by the gender of the believer. Feminism, on the other hand, is fundamentally a political and cultural agenda. The question of a woman’s biblically-based authority in Christ is not a question that concerns culture at large, but is rather a biblical and theological concern. Thus, a biblical egalitarian is not necessarily a feminist, and a feminist is not likely to be a biblical egalitarian.

How do you think that Christian egalitarians diverge from the politics of feminism?
