There is a reason why Dorothy Day is the patron saint of missional/emergent/emerging Christians:
Love of brother means voluntary poverty, stripping one's self, putting off the old man, deny one's self. It also means non-participation in those comforts and luxuries which have been manufactured by the exploitation of others. While brothers suffer, we must suffer with them. While our brothers suffer from lack of necessities, we will refuse to enjoy comforts. These resolutions, no matter how hard they are to live up to, no matter how often we fail and have to begin over again, are part of the vision and long-range goal of the catholic worker.
