This I conceive to be the darkest feature of slavery

Instead of preaching the gospel against this tyranny, rebuke, and wrong, ministers of religion have sought, by all and every means, to throw in the back-ground whatever in the bible could be construed into opposition to slavery, and to bring forward that which they could torture into its support. This I conceive to be the darkest feature of slavery, and the most difficult to attack, because it is identified with religion, and exposes those who denounce it to the charge of infidelity.
~ Frederick Douglass (May 12, 1846)
