Christians don't believe there's objective morality.

[Undeceived]

Christian morality is summed up in Jesus' words: "Love the Lord your God with all your heart and with all your soul and with all your strength and with all your mind; and love your neighbor as yourself." Love is good. Selfishness is evil. Jesus upheld the spirit of the law, rather than the letter of the law. The letter of the law is the actions Moses and other prophets commanded--they change. The spirit of the law is the mindset behind these commands. It has never changed.

You are speaking in generalities. When one does that and does not go to the specifics, one is able to cover up a multitude of sins. The fact is what is moral has changed over time and I'm prepared to enter into a formal debate with any Christian who is audacious enough to say nay. Do we have a place for formal debates in Atheist Forums?

How might I be more specific? Every action done out of love is morally upright. Every action done out of hate is 'wrong'. When we love, we are content. When we hate, our conscience eats us from the inside out. Cultural opinions on morality may change, but I think you'll find a 15th dynasty Egyptian and a modern American have very similar views on right and wrong. For example, the Egyptian culture may proclaim slavery okay so that it can practice slavery. Americans believe it wrong. But ask that Egyptian if it is morally okay to enslave him personally and you'll get a different response--one in line with the American's. With this strategy in mind, which morals do you feel have changed?
