The honor was named after a 1963 encyclical letter, Pacem in Terris (Peace on Earth), by Pope John XXIII that calls upon all people of good will to secure peace among all nations.
In other works, such as the cantata Pacem in Terris (based on the encyclical by Pope John XXIII), Gross used pertinent philosophical or political texts.
