An interesting phrase is found in one of the Apostle Paul’s letters concerning fallen angels and believers. There were numerous problems in the churches of Corinth with Christians taking one another to court over civil matters.  Within the assembly there were divisive factions due to social and economic differences.  Some were attempting to amalgamate pagan and Christian concepts into the mode of worship. As a result, the apostle had to strongly reprove the Corinthians for synthesizing Christianity and paganism.  It was in this setting that Paul raises the question concerning the judging of angels … “Do you not know that we shall judge angels” (1 Cor 6:3 NASB).  This is best understood in light of the Roman triumphal marches in which each soldier was assigned a prisoner to execute. If the unregenerate were capable of making decisions related to life and death, how much more should Christians be able to settle their differences apart from the heathen Roman courts.   Thus the apostle said … “I say this to your shame. Is it so, that there is not among you one wise man who will be able to decide between his brethren, but brother goes to law with brother, and that before unbelievers” (1 Cor 6:5-6 NASB)?  Why did Paul mention judging angels and who are these fallen angels of whom he is speaking?  Another apostle, John, gives us some insight into the angelic rebellion that occurred in eternity past.  “And his tail swept away a third of the stars [angels] of heaven, and threw them to the earth” (Rev 12:4 NASB).  Satan, then known as Lucifer, had sought make himself like the most High God and receive the worship of God’s creation.  Isaiah records “the five wills” of Lucifer (Isaiah 14:13-14).  Defeated in that rebellion and condemned to the lake of fire (Matt. 25:41), Satan and some of his angels attempted to prevent the seed of woman as promised in Genesis 3:15 from becoming a reality.  It appears that some of these fallen angels infiltrated the human race and procreated with women in an effort to destroy true humanity … “Now it came about, when men began to multiply on the face of the land, and daughters were born to them, that the sons of God [angels] saw that the daughters of men were beautiful; and they took wives for themselves, whomever they chose. Then the LORD said, "My Spirit shall not strive with man forever, because he also is flesh; nevertheless his days shall be one hundred and twenty years." The Nephilim were on the earth in those days, and also afterward, when the sons of God came in to the daughters of men, and they bore children to them. Those were the mighty men who were of old, men of renown. Then the LORD saw that the wickedness of man was great on the earth, and that every intent of the thoughts of his heart was only evil continually” (Gen 6:1-5 NASB). The result was the Great Flood.  We read of these adulterous demonic angels in the epistles of Peter and Jude.  “For if God did not spare angels when they sinned, but cast them into hell and committed them to pits of darkness, reserved for judgment; and did not spare the ancient world, but preserved Noah, a preacher of righteousness, with seven others, when He brought a flood upon the world of the ungodly; … the Lord knows how to rescue the godly from temptation, and to keep the unrighteous under punishment for the day of judgment” (2 Pet 2:4-5,9 NASB).  Jude adds … “and angels who did not keep their own domain, but abandoned their proper abode, He has kept in eternal bonds under darkness for the judgment of the great day” (Jude 6) NASB).  If Christians are to have responsibilities in the Kingdom of administering God’s justice, Paul admonishes the Corinthians and all believers thereafter to practice spiritual love (1 Cor 13), and if and when disputes arise between God’s people,  seek to settle them in accordance with Biblical principles rather than in the courts of law.
