Morality can only be objective with God. For, morality is about what is good action and what is bad. Now, to be good or to be bad is according to the fulfillment of the end of a something. For an instance, a good eyesight is an eyesight which can see clearly, for the end of eyes is to see. Now, the end of man is God, for man is created to know the truth and love the good, but God is the Truth and Goodness Himself, for all true and good things come from Him, because He is Being Himself, as proven by the arguments for God's existence. Therefore, without God, there can't be objective morality.
That's why, a government that is against natural law, is not a moral authority anymore, for the natural law shows what is good and what is bad by the use of reason alone, because by reason, we can know the nature and end of created things, and the end and nature of things are obviously the will of God, and God is the basis of objective morality, because that is not based from anyone's subjective major premise.
Hence, morality is not just about willing. It's about willing the truly good.
