Explain how one might apply the meta-ethics of Divine Command Theory to an egoist theory, a consequentialist theory, and a deontological theory.

It's egoist because it's imposed by an Almighty Power (God in this case), and even if you have the free will, one way or another, it's a condition to be good.

It's consequentialist because every choice you make, based on God's commandments, you will have a consequence, for the good or for the bad.

And finally, it's deontological because you are morally conditioned to choose, you don't have the option to put aside, it's a social convention to choose.

Explanation:

The Divine Command Theory address that everything that happens is based on the power and choice of an Almighty Power and humans are conditioned to choose. Even with the free will, the social and moral conditions demands a choice, that's why it's an egoist, consequentialist and deontological theory.
