In the vision of the world that Douglass offered his listeners, the highest ideal of a person was one who was like God. In a speech of the same name, Douglass argues that “Good men are god in the flesh.” Across a number of eulogies and public speeches, he extolls as examples of this his fellow abolitionists William Lloyd Garrison, Wendell Phillips, and Lucy Stone. In Douglass’s phrasing, Garrison becomes “the man–the Moses, raised up by God, to deliver his modern Israel from bondage.” Abraham Lincoln, he declares in a speech on “Great Men,” likewise, possesses “a more godlike nature than” any man he had ever met.
Douglass here says that good men are God in the flesh. What he means by that is God is working through them and it shows here on earth. He calls the other abolitionists he worked with these godly people.
