Some scholars argue that the main way of viewing the Atonement from the earliest Christians to the medieval era was as a 'victory' of God over the devil and the forces of death and darkness.
Associated with 'victory' is the theme of ransom; the souls of humanity were held by the Devil and a price needed to be paid for our release (Mark 10:45).
Gregory the Great (b 540CE) developed the idea that the devil had acquired the rights over fallen humanity and that the only way he could lose those rights was if he were to exceed his authority.
Jesus acted as a baited hook: the Devil thought he had control over Jesus as he did over all humanity; however, Jesus was sinless, and in killing Jesus, the Devil forfeited his power over human souls.
The 20th C theologian Gustav Aulén saw the Christus victor approach having appeal in the context of the two World Wars in terms of the darker sides of human nature they revealed and the need for spiritual liberation.
Belief in supernatural intervention was abandoned in favour of naturalistic explanations in the enlightenment; some focussed on Peter Abelard’s view (not an enlightenment thinker) of the cross as a sign of God’s love.
