Giles, a longtime egalitarian, establishes what the Bible actually teaches by critiquing biblical arguments for the permanent subordination of women; in other words, Giles critiques complementarian theology and methodology.
When rightly understood, Gen. 2:24-25 and Eph. 5: 21-33 provide an almost formula-like description for a pleasurable, loving, faithful marriage of oneness built on equality and mutuality. Modern science teaches what the writers of Genesis and Ephesians could not have known.
The Gospel According to Eve is a valuable resource for any egalitarian to have in their library. I also recommend it as assigned reading as part of a larger treatment or course on the history of interpretation.
