All value-systems or beliefs are simply human interpretations and essentially arbitrary

The idea of God becoming man encapsulates a religious version of the complete transfer of authority from the extrahuman or superhuman to the human.  But as to God, there is the prevalent posttmodern critique of the violence inherent in foundationalism of this ilk as there is a view of the  life-denying perversity of Christian morality.

Non belief or nihilism serves as an alternative to Christianity but as its redemption from metaphysics

thereby making of meaning from within a particular cultural moment rather than something read off from the way things really are.

For if all value-systems are simply human interpretations, surely none has any more claim on us than any other; all are equally subjective, hence essentially arbitrary and lacking in authority.
