Absence of goodThe absence of good (privatio boni), also known as the privation theory of evil, is a theological and philosophical doctrine that evil, unlike good, is insubstantial, so that thinking of it as an entity is misleading. Instead, evil is rather the absence, or lack ("privation"), of good. This also means that everything that exists is good, insofar as it exists; and is also sometimes stated as that evil ought to be regarded as nothing, or as something non-existent.
Ransom theory of atonementThe ransom theory of atonement was a theory in Christian theology as to how the process of Atonement in Christianity had happened. It therefore accounted for the meaning and effect of the death of Jesus Christ. It was one of a number of historical theories, and was mostly popular between the 4th and 11th centuries, with little support in recent times. It originated in the early Church, particularly in the work of Origen.
