States that God ordains humans with right reason to lead a moral life
Therefore, Morality can be discovered independently of God's commands so they're not abitrary, it is also universal
We use our right reason to understand the purpose of all things, which leads us to act morally (e.g purpose of sex = reproduction), our telos = human flourishing
Strengths of NML: think autonomy
Humans are viewed as more autonomous moral agents
No longer 'Slavish conformants' to a 'capricious tyrant' - Mackie
Athiests + Religious followers can co-exist
Weaknesses of NML: Think common nature + Nielsen
Relies on the understanding of a common human nature (e.g synderisis), evident that not all individuals possess this
Neilson: Human nature is subjective and a cultural phenomena, we do not all possess this desire, therefore = we do not all have right reason
Weakness of NML: Think final telos
Whilst it attempts to be accessible to all, e.g athiests and religious believers, this ultimately fails at it's final telos is believed to be God
