The lower half of Bishop Nussbaum’s personal coat of arms contains a “walnut tree”—the meaning of his name “Nussbaum” (remember the Christmas carol “O Tannenbaum”—a “fir tree” and hence the kind of evergreen tree used for a Christmas tree). The motto of Bishop Nussbaum, “Passio Christi in Corporibus Nostris” refers to the words of St. Paul and reminds the members of the Passionist Congregation that we bear “the passion of Christ in our bodies”.
