states that due to these dealings, Opus Dei's founder was declared a saint just 20 years after his death. In reality, Josemaría Escrivá was canonized 27 years after his death; admittedly faster than some others—but this is attributed to the streamlining of the canonization process and John Paul II's decision to make Escriva's sanctity and message known.

As many critics have pointed out, calling it The Da Vinci Code is like referring to Lawrence of Arabia as Mr. Of Arabia, or asking What Nazareth Do?".

The last leaders of the Knights Templar were killed in France in 1314 by King Philip IV of France, being burned at the stake on a small island in the Seine. Pope Clement's administration was not in Rome as he had moved the papal headquarters to Avignon. The Holy Blood and The Holy Grail The legend of the Holy Grail alleged that a sacred relic (in many versions, either the cup used at the Last Supper, or the cup said to have been used by Joseph of Arimathea to collect blood of Christ
