Viva La Vida

There are many interpretations of Coldplay's Viva La Vida. The following, extracted from Yahoo! Answers, appears to be quite plausible though not perfect.

If we analyse the lyrics, the song has obvious biblical references and I think it's a song about Jesus Christ.

I used to rule the world
Seas would rise when I gave the word
Now in the morning I sweep alone
Sweep the streets I used to own

All catholics should know that Jesus Christ gave the word and he controlled the seas - I think that the line now in the morning I sweep alone clearly means that Jesus Christ was betrayed and had to endure many things alone! The first verse is talking about a decline from wealth and fame to a nobody, just like Jesus Christ experienced on his life! He used to be a king, but he had to die for all human beings..So on a certain way he turned over his kingship (I used to rule the world). Clear reference of someone giving God kingship over his life.

I used to roll the dice
Feel the fear in my enemy's eyes
Listen as the crowd would sing,
"Now the old king is dead, long live the king!"
One minute I held the key
Next the walls were closed on me
And I discovered that my castles stand
Upon pillars of salt, pillars of sand


The line upon pillars of salt and pillars of sand, possibly is a reference to the sermon on the mount where Jesus speaks of a wise man building is house on a rock while the foolish man builds his house on the sand, only to be washed away.

Those days, there were different kings! Ones thought the king was Jesus Christ himself, others thought the king was the Roman authority and other thought the king was the Jewish priests.

I hear Jerusalem bells a ringing
Roman Cavalry choirs are singing
Be my mirror my sword and shield
My missionaries in a foreign field
For some reason I can't explain
Once you know there was never, never an honest word
That was when I ruled the world

Jerusalem bells and Roman Cavalry, it's obvious it's a biblical allusion. I think the line Be my mirror my sword and shield, it's a praying to God for strength. Also, the line my missionaries in a foreign field, has to do with the idea of taking the message of God and Jesus Christ all around the world. Finally, never an honest word, meaning the betrayal to Jesus Christ and his subsequent death.

I know St. Peter won't call my name, referring to the fact that Saint Peter denied Jesus 3 times.

It was the wicked and wild wind
Blew down the doors to let me in
Shattered windows and the sound of drums
People couldn't believe what I'd become
Revolutionaries wait
For my head on a silver plate
Just a puppet on a lonely string
Oh who would ever wanna be king?

This could be a reference to John the Baptist of the New Testament.
In The Book of Mark, John is noted as the one that comes before Jesus to announce His coming to Earth. A lot of people thought he (John) was going to be their Messiah, however he corrected them and told them that it was the One after him that would fill that role. I, also, argue that point because it is said somewhere that John's head was brought to king Herod on a Silver Platter.

Blew down the doors to let me in, meaning when Jesus Christ got furious because they turned the temple into a market!

EDIT: After thinking about it, the line "The old king is dead, long live the king" could be a reference to Jesus being on the cross. All of the people mocking him, and King of Jews above his head.
