Robert Adam's Modified divine command theory
In response to the arbitrariness problem
'There are certain expectations to the law of killing, made by the authority of God himself" - Augustine
Adams argues that because morality is grounded in the character of God, who is perfectly good, then God's commands are rooted in God's character
Since God is omnibenevolent, whatever God commands will reflect his character
Goodness is an essential characteristic of God so morality reflects this - it is intrinsic to his omnibenevolent nature
