The Ten Commandments

Christianity tells us that the commandments are guiding principles from God. Moses brought these commandments back from Mount Sinai on behalf of God. It's interesting to notice that the first three commandments are, how do you say, not really relevant compared to the rest. They even appear to depict a selfish god. One who is at some points claimed "omniscient", "omnipotent", but yet appears nervous that his subordinates might disobey his word. See for yourself.

The Commandments in order

1 — “I am the Lord thy God, thou shalt not have any strange gods before Me.“
2 — “Thou shalt not take the name of the Lord thy God in vain.“
3 — “Remember to keep holy the Sabbath day.“
4 — “Honor thy father and mother.“
5 — “Thou shalt not kill.“
6 — “Thou shalt not commit adultery.“
7 — “Thou shalt not steal.“
8 — “Thou shalt not bear false witness against thy neighbor.“
9 — “Thou shalt not covet thy neighbor’s wife.“
10 — “Thou shalt not covet thy neighbor’s goods.“

You'll find the Ten Commandments in the Bible's Exodus and Deuteronomy. They are supposedly provided by God as guidance to all people. They center around ethics and worship.

“And the Lord said unto Moses, Come up to me into the mount, and be there and I will give thee tablets of stone, and a law, and commandments which I have written; that thou mayest teach them. ...and Moses went up into the mount of God.“

— Exodus 24:12–13

“If you think that it would be impossible to improve upon the Ten Commandments as a statement of morality, you really owe it to yourself to read some other scriptures. Once again, we need look no further than the Jains: Mahavira, the Jain patriarch, surpassed the morality of the Bible with a single sentence: 'Do not injure, abuse, oppress, enslave, insult, torment, torture, or kill any creature or living being.' Imagine how different our world might be if the Bible contained this as its central precept. Christians have abused, oppressed, enslaved, insulted, tormented, tortured, and killed people in the name of God for centuries, on the basis of a theologically defensible reading of the Bible.“
