The famous statement, “the moral arc of the universe is long, but it bends towards justice” – borrowed by Dr. King from Unitarian minister Theodore Parker — implies that justice and equity and understanding evolve, usually more slowly than we would like. Abraham Lincoln and Charles Darwin not only knew this, but were born on the very same day (Feb. 12, 1809) and had more Unitarian ties than most people know. They both still have lessons for us.
