The authenticity of that letter has never been verified, but I’ll play Devils Advocate if you’ll pardon the expression.

The end of this war, people become disillusioned with Christianity could allude to the multitudes becoming aware go the weaponization & corruption of the teachings of Jesus. 

Lucifer has been a symbol of freedom
In many esoteric circles & a figure symbolizing revolution & challenging authority. 

To claim Zionism is wrong yet profess the Bible is correct could be seen as contradictory as the Israelites were Gods chosen and He would make a nation out of them. As the current nation of Israel is pretty close to the boundaries described in Genesis.

But the Bible having been translated & bastardized since its 1st translation into Greek could be seen as a weak reference.

All in all believe what you want mate but if you’re going to espouse a conspiracy at least know who wrote the letter. Pike was pretty open to criticism and liked to claim what he did & didn’t write.

Thank you & I look forward to a continued discussion.
