Abraham Lincoln actually said...
I do hereby further invite and request the heads of the Executive Departments of this Government, together with all legislators, all judges and magistrates, and all other persons exercising authority in the land, whether civil, military, or naval, and all soldiers, seamen, and marines in the national service, and all the other loyal and law-abiding people of the United States, to assemble in their preferred places of public worship on that day, and there and then to render to the almighty and merciful Ruler of the Universe such homages and such confessions and to offer to Him such supplications as the Congress of the United States have in their aforesaid resolution so solemnly, so earnestly, and so reverently recommended.
