The fact that God, or any other authority, commands me to do a certain thing is no guarantee that the command is right. It is I who must decide whether to accept the standards of any authority as (morally) good or bad. God is good only if His commandments are good; it would be a grave mistake—in fact an immoral adoption of authoritarianism—to say that His commandments are good simply because they are His, unless we have first decided (at our own risk) that He can only demand good or right things of us.
