How do we define "neighbor"?

                              Why Do Catholics Do That?
                              The Catechism of the Catholic Church teaches that our neighbor is someone whose origins we know and who deserves particular attention.  This includes our relatives since they share our origins.  Fellow citizens share residence in our country.  Anyone who is baptized is a fellow child of our mother the Church and shares our spiritual origin.  And every person is another child of God.
                              By all these definitions, we are responsible for looking after anyone who needs our help or care.
