This document contains 82 notable quotations from Luther on polygamy arranged by date. Some of these quotes can otherwise be difficult to find in English as not all he wrote has been translated from German. The quotations show he was at times rather conflicted by polygamy. It may be good to keep this document as a reference resource.
That's gold there. Thanks!
This one is humorous, it's a conversation between Luther and his wife, and from what I know of her personality I entirely believe it. To those who would say, "if a man is gody enough, his wife will go along with polygamy"...I give you Martin Luther. This is the man it is said could have been pope had he not been inspired to lead the Reformation. Martin jokingly called her 'the morning star', the irony of which is lost on everyone who reports it.
