What argument was the king making? Kings should not believe in God, for they are gods themselves. Kings are God's representatives on Earth, and they should not be challenged. Kings should agree that it is Parliament's job to run the government. Kings need to be more respectful of Parliamen

The argument that james made in the speech is:B. Kings are God's representatives on earth and should not be challenged.
Take a look at this part of the excerpt:
. . .for kings are not only God's lieutenants upon earth and sit upon God's throne. . .
From this line, we can infer that James see king as some one that given a direct authority from God to rule on his behalf. He wanted to showcase the difference in status between Kings and common people so he can justify the misbehavior that conducted by the Kings. helps this helps
