There are many people who claim "fulfilled prophecies" to the credit of their religions. There needs to be a way to judge a prophecy. I offer some criteria.
1> It must be possible to confirm that the prophecy was written before the event.
2> The prophecy must not be vague or cover a wide range of possible events.
3> The prophecy must not be indefinitely postponeable. There must be a point (assuming the prophecy does not come to pass) when we can declare that it has failed.
4> The prophecy must be independently verifiable. No source that has as part of its agenda showing the prophet valid is useful.
5> The prophecy must not have been fulfilled by people who knew about the prophecy and had an interest in fulfilling it.
6> The prophecy must have been understood as a prophecy before fulfillment.
7> The prophecy must not be something that would be expected anyway. (E.g. it will rain this year.)
