James 2:8
If you really keep the royal law found in Scripture, 'Love your neighbor as yourself,' you are doing right — the 'royal law' (nomos basilikos) draws from Leviticus 19:18 and stands as the summary principle of authentic righteousness, functioning as a canon within the canon. The law is 'royal' not merely because it comes from a monarch but because it represents the fundamental principle of God's kingdom. To keep this law is to 'do well' (kalōs poieite), establishing love as the criterion for ethical behavior.
