Yearly Meeting 1822 accepted ‘An address to the inhabitants of Europe on the Iniquities of the slave trade, issued by the Religious Society of Friends’:

The arguments of the Christian, like the religion from which they are derived, are plain and simple, but they are in themselves invincible. The gospel of our Lord Jesus Christ is a system of peace, of love, of mercy, and of good-will. The slave trade is a system of fraud and rapine, of violence and cruelty… That which is morally wrong cannot be politically right.
