A somewhat scarce badge here. This membership badge would have been used by a patriotic women's association associated with the protestant church. No major damage is present, enamel is in good condition (as seen in photos). Working pin and catch to the reverse along with clear maker's mark from PH. Wondra, Darmstadt. 
 
Based on the fact that all women's organizations were absorbed into the Frauenwerk/Frauenschaft during Third Reich, this badge is likely WWI/Weimar era manufacture.
