Ok, I was trying to grasp what you meant by literal. I am probably somewhere around Amillenialism or Classical Preterism but it doesn't matter to me a lot to be one or the other.
The Binding of Satan some would say means not total exorcism of all demons from this world as I read some say Karl Barth believed. But Barth's views on that are quite complex. He seems to have thought the demons where never angels in the first place, and sees the devil's power as the power of lie. In the regard to the latter it completely aligns with Scripture.
Is it pious opinion that the devil was previously Lucifer or is it revealed in Scripture? Thomist scholar Josef Pieper offers this thought on the subject. Right from the beginning he says the angels stood at the end of their "pilgrimage".
"Even the angels whether blessed or fallen, were once, in the strict sense, viatores, "on the way". But their "way" was not temporality (which again, does not mean they shared in the eternity of God). For the angel, the status viatoris was a single instant - "instant", too refers to time, but we are unable to think in anything but a temporal mode - an instant in which the angel was able to make an intellectual decision for or against God. From the first moment of his existence, the angel stood "at the end of his pilgrimage"; the duration of a single unpropitious act of decision separated him from his goal. For the angel, this act put an end to the status viatoris." (Josef Pieper - On Hope)
Probably not a reference to Satan, or the devil, in Bunyan's classic Pilgrims progress, the Pilgrim encounters two fierce lions on his journey at one point, two of his companions take fright and won't continue with him, but Pilgrim carries on and discovers the lions are chained, and that by keeping in the centre of the path and not straying to either side, they cannot reach him or harm him.
Charles Spurgeon thought the lions in Pilgrims Progress represented difficulties, or anxiety about intially joining a church, because Pilgrim encountered them when they were on the way to the house Beautiful which is Bunyan's figure for the Church.
