Fr. Berrigan took the Gospel seriously, taught it faithfully, lived it consistently.  What if everyone followed his teaching?  What would we have then?  Peace??  His life and ministry point us forward to the time when the work of building the Kingdom will be complete and the Son will hand it over to the Father; but they also point us back to the time when the earliest Christians shared everything in common and eschewed violence and military service. We live in the "time between the times" (the time between the First Coming of the Lord and the Last), and we find our bearings by reflecting on where we've been and where we need to go.  Father Berrigan helped, and helps, us to do that.
