Are the values we hold 'Christian values'?

[Mr Khan]

There is a rational basis for morality: utilitarianism. It is a rational basis for the Golden Rule and assuming that given the equality of our human desires, properly run utilitarianism sets up protections against moral relativism, because evil actions "for the greater good" are not justifiable if a better alternative is available, which is almost always the case

Utilitarianism solves most moral dilemmas without having to resort to religion, or, for that matter, any of Immanuel Kant's a priori categorical imperative nonsense. Though the categorical imperative is another rational basis for morality, it is much less straightforward, appealing to nontangible (yet non-spiritual) things.
