You cited one of my favorite Pauline passages .. Galatians 5 as well. 14 For the entire law is fulfilled in keeping this one command: “Love your neighbor as yourself.
Who says Satan is Lawless .. certainly not the story of Job ? .. Clearly he had the permission of "The Most High" - his Father to be present at this function in Heaven .. The advocate has a one on one conversation... with his Father. "How are things Going God asks .. what have you been up to" .. down around on earth abound :) you know the story. Father boats to the son .. have ya seen me servant Job .. Son ribs his father . well yeah dad .. you gave him everything .. try taking that away and see what happens.
The bet is made .. and the terms are set. Satan goes out to do his duty as a tester ... and he has some serious powers .. "Godlike- Powers".
But - Satan does not step beyond God's rules .. Satan abides by them .. and the Son's of God are always shown as "subservient" to the Father. Subordinate to the Father .. as the Early Church believed about Jesus .. for a long long time .. until an evil Emperor changed things - and even after that it took another 400 years for this belief to be stomped out by the sword .. and another 600 years of horror to make it stick .. thus completing the 1000 years of horror.
Deut 32:43 .. the real version .. the one the early Church was using and not that joke of a modern Translation.
O heavens, rejoice with Him Bow to Him, all divinities Bow to Him, all sons of the divine --- (Sons of God)
O nations, rejoice with His People And let all angels of the divine Strengthen themselves in Him.
For He’ll avenge the blood His sons, Be vengeful And wreak vengeance And recompense justice On His foes, Requite those who reject him and the Lord will and Cleanse His people’s land.
The Son's of God are bowing to The Most High .. but also rejoicing and celebrating with him in Heaven.
On a lower level are the nations .. and "His people" meaning the Israelites .. the Angels are on a lower level yet.
I am sure the Advocate was invited to that party as well..
Satan must not have been at this party though Psalm 82 .. Where "El" God of Abraham is seated as the head of the Divine Council .. YHWH is prosecuting the other "Sons of God" - condemns them to death .. and takes over their people .. takes over all the nations of the earth for himself.

We know this because Satan is still around in Mark. once again in his role as "Tester" .. a role given to him by the Most High.
Then one day someone has a bad dream about some evil demons and attributes this to the Tester .. Satan gets such a bad wrap .. He is actually the doorman when you get to heaven .. good one too .. like a consierge . gives good advice .. what some of the good vacation spots are .. :)
