Furthermore, "know Saint peter will call my name" followed by "never an honest word". Could speak to the discouragement the singer/knight feels when he's ultimately betrayed by the church/state that he served in the name of "God". Knights in the Crusades served the church and wore a cross on their chest. When the Templars fell, they were tried for heresy and burned at the stake or tortured, to admit their guilt. This for those who marched and gave their lives for the Church, "to get to heaven". It was thought that to partake of the Crusades was a "holy war" which is a way to do works to get to heaven. So "knowing he would call your name" followed by "never an honest word" might refer to the feeling the "judged knights" would feel against the church that condemned them to imprisonment and in some cases death.

I think this song refers to the ascent to power by a person who has followed a call to be a righteous warrior king. Kind of like the Knights Templars. They ruled the world, in the sense of a "holy Crusade" the bells ringing refers to the Roman Empire ways of those who followed organized religion. And following God, is looking in the mirror. But his delusion was thinking he could as a man rule the world and power corrupted, or he fell. Now that he's returned from his lofty position of power, he's just left and despised as a failed warrior, ready for death. Knowing Peter will call his name speaks of the former and possible state of mind that he's on his way to heaven, but now humbled, because he's no longer a king, just a janitor sweeping the streets. If you read about the Crusaders and the Knights Templars who were the Popes private army this kind of makes sense. It's an allegory of sorts, toward any "warrior or King for God" who thinks they are the man. Used to rule the world, is the key.
