Opus Dei and other 'elitist' groups see themselves as the "purest of the pure".  The Jews were God's chosen people.  But God taught them that He [She] had love and concern for other peoples.  The story of the Prophet Jonah is a reminder of that.  God told Jonah to preach repentance to the people of the great city of Nineveh.  Jonah disliked these non-Jewish people very much.  When he tried to sail away from the city, a horrible storm arose and the captain and sailors, which Jonah's permission, tossed him overboard.  God provided a watery taxi [large fish---whale?] to swallow Jonah and deliver him to the front 'porch' [shore] of Nineveh.  It's a humorous story---but it gets the point across.  Jesus did the same centuries later, by telling the story of the Good Samaritan [Jews hated them], but praising the faith of non-Jews in his meeting with them.
