Thanks to Bob Miller for showing me this quotation from John Chrysostom (c. 347-407) from his Homily 5 on Titus:
“Woman was not made for this, O man, to be prostituted as common. O you subverters of all decency, who use men, as if they were women, and lead out women to war, as if they were men! This is the work of the devil, to subvert and confound all things, to overleap the boundaries that have been appointed from the beginning, and remove those which God has set to nature.”
This early Church Father is not just ranting and raving; rather, he suggests a whole approach to issues like these: What are we made for? What are the “boundaries,” or do you really think we can do without any boundaries at all?
