The spiritual part never changes. All the Manifestations of God and His Prophets have taught the same truths and given the same spiritual law. They all teach the one code of morality. There is no division in the truth. The Sun has sent forth many rays to illumine human intelligence, the light is always the same.
The practical part of religion deals with exterior forms and ceremonies, and with modes of punishment for certain offences. This is the material side of the law, and guides the customs and manners of the people.
- ‘Abdu’l-Baha (‘Paris Talks’)
