Wartime Pope Pius XII knew details about the Nazi attempt to exterminate Jews in the Holocaust as early as 1942, according to a letter found in the Vatican archives that conflicts with the Holy See's official position at the time that the information it had was vague and unverified.
The yellowed, typewritten letter, reproduced in Italy's Corriere della Sera on Sunday, is highly significant because it was discovered by an in-house Vatican archivist and made public with the encouragement of Holy See officials.
The letter, dated Dec. 14, 1942, was written by Father Lother Koenig, a Jesuit who was in the anti-Nazi resistance in Germany, and addressed to the pope's personal secretary at the Vatican, Father Robert Leiber, also a German.
