23 and he having turned, said to Peter, `Get thee behind me,
adversary! thou art a stumbling-block to me, for thou dost not mind the things of God, but the things of men.` Mt 16
I know that Satan tempted Christ. He tempted Him not to go to the cross, but to disobey His Father..
I know you know just how weak the stand is you're taking on this passage. There is no indication that 'the devil' entered into Peter, or that permission was obtained as required in Luke 22:31. The word satan was used here in it's primary sense:
1. adversary (one who opposes another in purpose or act),
"...there is no evidence that the Lord Jesus meant to apply this term to Peter, as signifying that he was Satan or the devil, or that he used the term in anger. He may have used it in the general sense which the word bore as an adversary or opposer; and the meaning may be, that such sentiments as Peter expressed then were opposed to him and his plans. His interference was improper. His views and feelings stood in the way of the accomplishment of the Saviour's designs...."
Barnes Notes On The Bible
And in no way has 'the devil' ever minded the things of men. He makes them sick and diseased and demon possessed and causes misery among them.
Your position is weak. Lame.
