Answer:
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.

Even with the free will, the social and moral conditions demands a choice, that's why it's an egoist, consequentialist and deontological theory.
