I absolutely see this song being written from the eyes of jesus. Maybe I'm being repetitive of what other people have already said but I'm going to say it anyway. The church used to rule everything people did, so much so that government had to create a separation between church and state. Now the church is falling apart and churches are closing because they can't afford to stay open. This is also apparent in the third stanza which states at one point he held the key but now everything is falling apart and its like his empire was built on sand as it collapses before him. I believe the chorus is about his crucifixion and that its not the roman "cavalry" but the Roman "Calvary". Calvary or Golgotha are the English language/Western Christian names given to the site, outside of ancient Jerusalem’ s early 1st century walls, ascribed to Jesus's crucifixion. In other words, the roman calvary is where jesus was crucified. The lyrics then say be my mirror. I believe this is jesus asking people to tell others about him and defend his purpose by being his sword and shield. The next stanza when it talks about the wicked and wild wind, when jesus finally died on the cross a horrible storm came over the land, windows and doors were broken and the curtain inside the church tore itself in half. When he was resurrected no one would believe it until they saw him for themselves, hence the "people couldn't believe what i'd become." Being a puppet on a string represents how he was there acting for god and was in a way god's puppet. When it says " for some reason i can't explain I know saint peter wont call my name" its referring to when saint peter denied jesus three times just as jesus said he would. This is the most logical explanation from my point of view. Let me know what you tihnk.
