If you fulfill the royal law according to the scripture, You shall love your neighbor as yourself, you do well:…
The law may be called "royal" or "kingly," either —
1. In the sense in which Plato speaks (Minos 2:566), of a just law as kingly or sovereign, using the same adjective as St. James, or —
2. As coming from God or Christ as the true king, and forming part of the fundamental code of the kingdom. In a Greek writer the first would probably be the thought intended. In one like St. James, living in the thought of a Divine kingdom, and believing in Jesus as the King, the latter is more likely to have been prominent.
