“At one time this tract was viewed as a very ancient product—as early as A.D. 70 or 90. Recent study, however, has conclusively shown that, in the form we have it, it belongs to the second century.

It has appropriately been called the “spoiled child of criticism”; and it will probably need a good deal more spoiling before its riddle is finally solved.”
