From the transcript linked above:
As we approach Mother's Day this Sunday, we take a look at the woman behind Mother's Day, Julia Ward Howe. Yes, she is the author of the Battle Hymn of the Republic but after seeing some of the devastating effects of the Civil War- death, disease, famine and poverty - she began advocating for a mother"s day for peace in 1870.
Mother's Day Proclamation, written in 1870 by Julia Ward Howe, as a call for women around the world -- men, too, of course -- to listen to a public voice and then answer it themselves.
Arise, then, women of this day. Arise all women who have hearts, whether your baptism be that of water or of fears. Say firmly, we will not have great questions decided by irrelevant agencies. Our husbands shall not come to us wreaking with carnage for caresses and applause. Our sons shall not be taken to us to unlearn all that we have been able to teach them of charity, mercy and patience. We women of one country will be too tender of those of another country to allow our sons to be trained to injure theirs. From the bosom of the devastated earth, a voice goes out with our own. It says, disarm. Disarm. The sword of murder is not the balance of justice. Blood does not wipe out dishonor nor violence indicate possession. As men have often forsaken the plow and the anvil at the summons of war, let women now leave all that may be left of home for a great and earnest day of counsel. Let them meet first as women to bewail and commemorate the dead. Let them solemnly take counsel with each other, as the means whereby the great human family can live in peace, and each bearing after her own time the sacred impress, not of Caesar, but of God.
