Full Preterism is a system that demands a priori reasoning. Its logical method is not optional, but required. Typically it starts with a “necessary” truth, such as that “all prophecy was fulfilled in A.D. 70.” Then it proceeds to filter out the evidence, working from an assumption to its logical conclusions. In the course of his studies, the interpreter will sometimes make use of the inductive method: but only to verify and confirm his assumptions. Whenever these assumptions are confuted by Scripture evidence, he tampers with the facts, often deliberately confusing their meaning or displacing their context. Sometimes he just ignores them.
