In light of this verse
“Do you not know that we are to judge angels? How much more, then, matters pertaining to this life!” 1 Corinthians 6:3
And taking into account that aggelos is a messenger, therefore a vocation description rather than a description of their being and attributes. Directing attention to their being
“Are they not all ministering spirits sent out to serve for the sake of those who are to inherit salvation?” Hebrews 1:14
Is it therefore possible that not all heavenly hosts that have erred and await judgment are fallen? Is the passage in Corinthians an indication that they are not fallen? Or though fallen they are still angels? But at a minimum, either or, are under God’s jurisdiction?
For what shall we say of this example
“Then a spirit came forward and stood before the Lord, saying, 'I will entice him.' And the Lord said to him, 'By what means?' And he said, 'I will go out, and will be a lying spirit in the mouth of all his prophets.' And he said, 'You are to entice him, and you shall succeed; go out and do so.'” 1 Kings 22:21-22
Was this an “angel” or a fallen one?
We know satan has been judged and possibly all the rebelling sons of God as per Deu 32:8DDS and Psa82
“The Lord has broken the staff of the wicked, the scepter of rulers, that struck the peoples in wrath with unceasing blows, that ruled the nations in anger with unrelenting persecution.” Isaiah 14:5-6
This is judgment. And we can confirm that satan has been judged
“concerning judgment, because the ruler of this world IS judged.” John 16:11
Therefore unless they await further judgment they are excluded from the Corinthians passage.
