The best/most enlightening commentary I've found so far:
Suppose that sometime around the year 3,800 A.D., someone wrote a newspaper that began: "According to a recently-discovered document, which appears to have been written sometime before 1926, Benedict Arnold did not attempt to betray George Washington and the American cause, as is commonly believed. Rather, Benedict Arnold was acting at the request of George Washington, because Washington wanted Arnold to help him create a dictatorship of the proletariat and the abolition of private property."Do enjoy the whole thing.
A reader who knew her ancient history would recognize that the newly-discovered "Arnold document" was almost certainly not a historically accurate account of the relationship between George Washington and Benedict Arnold. The reader would know that the terms "dictatorship of the proletariat" and "abolition of private property" come from a political philosophy, Marxism, which was created long after Washington and Arnold were dead. The reader would also know that the most reliable records from the 18th century provided no support for the theory that Washington or Arnold favored a dictatorship of the proletariat or the abolition of private property.
This Friday's coverage of the so-called "Gospel of Judas" in much of the U.S. media was appallingly stupid. The Judas gospel is interesting in its own right, but the notion that it disproves, or casts into doubt, the traditional orthodox understanding of the betrayal of Jesus is preposterous.
