Christians affirm that sex is a wonderfull gift from God, but that like all gifts it is open to abuse. Christians would want to say that pornography is anti-normative to God’s creational purposes for individuals, relationships and society.
A recent conference ‘The Social Cost of Pornography’ has sought to highlight the effect which pornography has on a society. This is interesting reading which supports, from a non biblcial/theological perspective, the view that pornography is not simply harmless fun but has a negative impact on individuals, relationships and society. The papers of this conference can be found here.
