My views on objective morality

[Neo-Scholastic]

...I came up with that argument on my own. I didn't know Euthypro's Dilemma existed as such until reading this thread.

If you say so.

Your rejection...is that God uses himself as the standard for goodness because he is the very essence of goodness (or something like that).

Something like that.

Aside from being completely circular...

Only if you ignore the context and history.

If God decided to use his own qualities as the standard for good, then it's still arbitrary and based on nothing more than divine command.

Your objection is based on the irrational idea that God could act contrary to His nature. The only thing arbitrary is the personal choice of whether or not to accept God's Nature as the object of moral reasoning. Virtue ethics argues that it is both wise and praiseworthy to do so.
