If other churches pick up on Pope Francis's initiative, there's hope that religion and science may yet get on the same page of life with respect to the existential matter of people confessing the oneness of human life with earth ecology. Keep pushing pope Francis! Except churches do come together, there is little hope people will; joining theologies on common ecological grounding is not enough. What about global politics? 
It's less likely that politics are ready to join in this understanding -- much less likely to make the political decisions guided by ecological sanity -- especially when churches have no moral vision respecting universal ecological belonging. Particularly frightening at this moment is the me-first thinking of our president-elect.
This existential crisis of ecological disconnect confronting humankind, more than any other, calls for CHURCHES UNITED; when churches get the theology of nature wrong, how can we trust that their conflicted theologies are right?
