Atonement doctrine teaches that Jesus life in the flesh, together with his death on the cross and subsequent resurrection, was the ransom which had thus been paid in order to purchase man back from the clutch of the evil one —from the condemnation of an offended God. 
The doctrine of a personal devil on Urantia, though it had some foundation in the planetary presence of the traitorous and iniquitous Caligastia, was nevertheless wholly fictitious in its teachings that such a “devil” could influence the normal human mind against its free and natural choosing.  The devil has been given a great deal of credit for evil which does not belong to him. 
The Jewish traditions of heaven and hell and the doctrine of devils as recorded in the Hebrew scriptures, while founded on the lingering traditions of Lucifer and Caligastia, were principally derived from the Zoroastrians during the times when the Jews were under the political and cultural dominance of the Persians.  Nobody should knowingly to ascribe the works of God to the doings of devils.  “Man is the son of God, not a child of the devil.” Mortal man was never the property of the archdeceivers.  Sanhedrin attributed Jesus’ works to power of devil, and that he was a child of the devil.  Jesus said: “Once and for all be delivered from the superstition that God afflicts man at the behest of the evil one”.
