If it is a ransom paid the devil, I don't believe this is Scriptural. God owes Satan nothing. Period. Other than a swift kick in the butt into the lake of fire. But, I will await your answer.
But that's the meat of it, Blogger! Satan triumphed when Chirst died. But that was short-lived because Satan soon realized that he was duped, as +John Chrysostom says in his Easter homily, 1600 years ago, "Death took the body, and found God." Oooops!
"If it is a ransom paid the devil, I don't believe this is Scriptural. God owes Satan nothing."
You're right. God doesn't owe the Evil One anything. More later. :)
