Without a universal absolute, we have no foundation to say that Pedophilia is or isnt wrong.
Our abhorrance of paedophilla has strengthened as we understand more about the psychological damage it can cause. In the same way our view of slavery has changed through the centuries as we realised that their is no such thing as an inferior race. This IMO demonstrates the subjectivity of morals and how increased knowledge moves our moral goal posts.
Incidently neither of the above are condemned by that monstrous book "The Bible".
