Below is the Vatican flag representing the aims and ambitions of the Papacy. You can see 2 keys, a gold key and a silver key. The gold key symbolises the Papal claims that the Papacy is the only true authority in the Spiritual realm.
The silver key symbolises the claim that the Papacy is the only true ruler in the temporal realm, it really means that the Pope is the only legitimate ruler of the world`s nations, as far as the Church of Rome is concerned.

Silver Key and Gold Key

The symbol below is the crest of the National Security Agency of the United States.  You can see the silver key on it. Why it is there?

It is there to show that the NSA is in actual fact an agency which soley exists to further the the temporal rule of the Vatican in the USA and worldwide.

What is more, they do not care who knows about it, they are so sure of themselves they do not even try to hide  the fact.

The official symbols of the United States and its many different agencies really do tell a tale but hundreds of millions of American citizens cannot see it. Even though the truth is staring them right in the face and screaming out at them.

Silver Key, the temporal power of the Papacy

Luke 8:10 And he said, Unto you it is given to know the mysteries of the kingdom of God: but to others in parables; that seeing they might not see, and hearing they might not understand.

seeing they might not see, and hearing they might not understand.
