Irenaeus was the great champion of early Chiliasm. He probably wrote in the clearest detail and had the greatest influence of all the early Chiliasts. His origins were notable in from Asia Minor. Notwithstanding, he was Bishop of Lyons, Gaul from where he wrote extensively. He was believed to have died around AD 155–156. Like ancient and modern Amillennialists, Irenaeus believed in the current binding of Satan. He believed this happened through the life, death and resurrection of our Lord. He also believed in the destruction of Satan at the second coming. This meant he did not see him arising 1000 years after the second coming and raising up a mammoth insurrection in the next age. This too is in keeping with classic Amil position. Irenaeus was very direct, consistent and bold in his declarations on the binding of Satan.
He declares:
For as it was not possible that the man who had once for all been conquered, and who had been destroyed through disobedience, could reform himself, and obtain the prize of victory; and as it was also impossible that he could attain to salvation who had fallen under the power of sin, - the Son effected both these things, being the Word of God, descending from the Father, becoming incarnate, stooping low, even to death, and consummating the arranged plan of our salvation (Against Heresies Book 3, Chapter 18, 6:2).
Irenaeus lays out the great assignment that Christ undertook on man’s behalf. He highlights the pitiful condition of man. He simply couldn’t help himself. He was in too depraved a state. He needed someone stronger to liberate him. Christ was indeed a man on a mission coming to rescue man from his own self-destruction. Satan was a distinct obstacle to this assignment. After all, man had given the evil one authority over his life that he did not deserve. So, the devil had to be confronted and overcome on his own playing field. That is what Jesus did:
For He [Jesus] fought and conquered; for He was man contending for the fathers, and through obedience doing away with disobedience completely: for He bound the strong man, and set free the weak, and endowed His own handiwork with salvation, by destroying sin. For He is a most holy and merciful Lord, and loves the human race (Against Heresies Book 3, Chapter 18, 6).
Irenaeus, here, significantly, links the binding of Satan to Christ “destroying sin.” This of course is a direct reference to the cross-work. The ancient writer saw Christ’s first coming as an overall mission to defeat the wicked one and save men. Both of these go hand-in-hand in the early Chiliast’s assessment of Christ’s earthly ministry. This explains how Calvary is at the core of the early Millennialists’ attitude to the subjugation of the devil. There, Jesus fully overcome sin and death.
Without this transaction the Gentiles would never have been set free. Before the cross the Gentiles were in blind ignorance, deceived by the father of lies. After the resurrection, the Gentiles were no longer deceived as the Gospel light shone throughout the nations. The veil of ignorance was lifted. They are now without excuse. Satan had them hoodwinked. They lay in darkness. He ruled the nations before the death, burial and resurrection of Christ. He had them under his control.
Irenaeus continues:
By means of the second man did He bind the strong man, and spoiled his goods, and abolished death, vivifying that man who had been in a state of death. For at the first Adam became a vessel in his (Satan’s) possession, whom he did also hold under his power, that is, by bringing sin on him iniquitously, and under colour of immortality entailing death upon him. For, while promising that they should be as gods [talking about the lie of Satan in the Garden], which was in no way possible for him to be, he wrought death in them: wherefore he who had led man captive, was justly captured in his turn by God; but man, who had been led captive, was loosed from the bonds of condemnation (Against Heresies Book 3, Chapter 23, 1).
Irenaeus saw the First Advent as securing the overall defeat of every enemy of God and righteousness. He saw it as a full package. Christ came (on assignment) to undo all the result of the Fall. His life, cross-work and triumphant resurrection was pivotal in defeating our arch-enemy. The binding was not limited to Christ casting out demons, although this was an integral part of His overall mission. The cross and the resurrection was the triumphant apex of His earthly task. This is where sin was fully paid for, death was defeated and Satan was stripped of his then immense power and widespread control.
Ironically, this is the verbiage of Amillennialism. As a result of the First Advent, Satan is shown to be a prisoner – he is a captive. The spiritual prison man was incarcerated in prior to the cross and the chains the evil one had him incapacitated with were in turn placed upon Satan. The boot was on the other foot. The shackles that bound them have now been placed upon Satan. The devil is thus seen as a vanquished foe. Christ’s earthy ministry is seen to loosen what the enemy had afflicted all mankind with. By doing this, he resolved the sin issue, and overcome the death issue (the consequence for sin).
Irenaeus understood the binding of the strong man 2,000 years ago related to the victory Christ won over Satan and Him spiritually establishing God’s Kingdom on the earth and invading the kingdom of darkness with the light of the Gospel and seeing the ignorance banished amongst the Gentiles. Satan can persecute, he can deceive, he can even destroy the body. But he cannot stop the light of God’s truth, (the good news of the kingdom) from going into the nations. He cannot prevent anyone from repenting and confessing Christ. This is completely up to the individual.
How, too, could He have subdued him who was stronger than men, who had not only overcome man, but also retained him under his power, and conquered him who had conquered, while he set free mankind who had been conquered, unless He had been greater than man who had thus been vanquished? But who else is superior to, and more eminent than, that man who was formed after the likeness of God, except the Son of God, after whose image man was created? And for this reason He did in these last days exhibit the similitude; [for] the Son of God was made man, assuming the ancient production [of His hands] into His own nature, as I have shown in the immediately preceding book (Against Heresies Book 4, Chapter 33:4).
Irenaeus links the subduing of Satan to Christ's death 2000 years ago. The enemy is shown here to be currently vanquished. This is the opposite of Premil theology. What is more: he relates the binding of Satan at the First Advent to “these last days” – showing the reader that they had already arrived.
