When St. John who recorded the vision God gave him as a revelation was banished to Patmos!?

Do you really think God gave him this vision to p down so people can ume its meaning or to prove to people that they have no clue of the exact meaning of this vision. As representative metaphors or factual descriptions, what man can ume he has figured out its meanings to mislead the nations. Did God not tell use that those who listen will be blessed but that those who claim understandig will be made fools. What approaches did st. Johns enemies take to disprove him before they banished him to Patmos. God Bless all...
