Dear Emmett,
We have a LOT of work to do, and it will take a long, long time to reconcile the many ways that racism continues to divide us and perpetuate the social sins that happen every day.  But we are not doomed.  God is speaking, and we need to listen.  Fr. Massingale actually did list some steps that the Catholic Church can take (go to YouTube, look up  racism and the catholic church), but the more important question is what are we going to do?  We could pray.  Listen with an open heart and mind.  Read (e.g. "Just Mercy" or the examples below).  See the face of God in everyone.  Start conversations in our own church, family and friends -- for example, watch Fr. Massingale's YouTube or read a book about racism together and then talk about it.  Discern specific things our local churches can do.  You may have other ideas.
