We have no doubt that faith-based communities have played a significant role in community transformation, and that there are many opportunities for that role to expand further. And we are sure that a book (or many books) could be written about it.
But to give you a start toward clarifying your own answer, we can point you to two sources: One is a short bibliography on faith-based resources for action, published by the Asset Building Community Development Institute at DePaul University, at https://resources.depaul.edu/abcd-institute/resources/Pages/Faith-based-Resources.aspx. The other is a report from the Center for Religion and Civic Culture at the University of Southern California, at https://crcc.usc.edu/report/community-transformation-outlining-a-process-for-change/.
We hope these sources may help further develop your own thinking and action. All best wishes as your efforts continue.
