Friends, I urge you to read the letter from Barth to Madame Visser 't Hooft that Tim has posted here.
Not only are you unlikely ever to see this letter anywhere else, I can assure you that you will find Barth's response to Mrs. Visser 't Hooft's proto-feminism bracing, remarkably biblical and unbending.
For more background on Henriette Visser 't Hooft's proto-feminism, the difficulties it caused her husband (a leader in the WCC ecumenical movement) and Barth's scathing response, see this fascinating article (though sympathetic to Mrs. Visser t' Hooft) by Jurgen Moltmann.
