To appreciate its importance we must not consider it as a single independent act standing alone, nor as one pertaining to this District only, nor to the colored people only. We must regard it as a part of a series of splendid public measures, as one of so many steps in the national progress looking to one beneficent and glorious result, a large contribution to the honor and welfare of the whole country. It was the auspicious beginning of a great movement in the councils of the nation, made necessary by the war, and one which finally culminated in the complete and permanent abolition of slavery, not only in the District of Columbia, but in every part of the Republic. Thus viewed it was the one act which broke the gloomy spell that bound the nation in the bonds of servile, unnatural reverence and awe for slavery. It withdrew the sympathy of European nations from the rebellion; it brought the moral support of the civilized world to the loyal cause; it erased the foulest blot that ever stained our national escutcheon; it gave to the war for the Union a logical, humane, and consistent purpose; it solved a problem which was the standing grief of good men, and the perplexity of statesmen for ages; it gave courage and hope to our armies in the field; it weakened the rebellion; it raised the whole nation to a higher and happier plane of civilization, and placed the American people where they never were before, in a position where they could consistently and effectively preach liberty to all the nations of the world. The 16th of April, the anniversary of this great act of the nation, strangely and erroneously enough has been considered simply as the colored man’s day only. The business of consecrating and preserving its memory has been, by common consent, relegated to him exclusively. But, in this, our fellow-citizens have been more generous to us than just to themselves. Colored men have very little more reason to hallow this day than have white men. If it brought freedom to us, it brought peace and safety to them, and hence they may well enough unite in this and similar celebrations, and regard the day as theirs as well as ours. No truth taught by our national history is more evident than this, that while slavery dominated the southern half of the Republic, and free institutions prevailed in the northern half, peace and harmony between the two sections were utterly and forever impossible. No man can serve two masters, and the attempt of our Government to do this was a stupendous failure. The union between liberty and slavery was a marriage without love, a house divided against itself; a couple unequally yoked together, held together by external force, not by moral cohesion; it brought happiness to neither, and misery to both.
