To His Excellency the President of the United States.
By your order of the 16th day of November, 1862, you recommend that the officers and men of the army shall observe the Sabbath and do no work on Sunday, because we are a Christian people. But according to the Declaration of Independence and according to the constitution of the United States, the people of the United States is not a Christian people, but a free, sovereign people with equal rights, and each and every citizen of the United States has the right and liberty to live according to his own consciousness in religious matters, and no one religious denomination, be it a majority or minority of the people, can have a privilege before the other under this our beloved constitution.
Now by the order of your Excellency you give the privilege to those officers and men in the army who by their religious creed do observe the Sunday as a holy day and a day of rest; but you make no provision for those officers and men in the army who do not want to observe the Sunday as a holy day, (as for instance those Christians called the Seventh-day Baptists and the Jews, who observe the Saturday as a hold day and a day of rest,) that they may enjoy the same privilege as those who observe the Sunday as a holy day, as well as for the heathen or the so called infidels, who do not want to celebrate either the Sunday or the Saturday as a Sabbath, but choose perhaps some other day as a day of rest.
Now I stand before you as your namesake Abraham stood before G-d Almighty in days of yore, and asked, "Shall not the Judge of all earth do justice?" so I ask your Excellency, the first man and President of all the United States, Shall you not do justice? shall you not give the same privilege to a minority of the army that you give to the majority of it? I beseech you to make provision, and to proclaim in another order, that also all those in the army who celebrate another day as the Sunday may be allowed to celebrate that day which they think is the right day according to their own conscience; and this will be exactly lawful, as the Constitution of the United States ordains it, and at the same time it will be exactly according to the teaching of the Bible, as recorded in Leviticus xix. 18: "Thou shalt love thy neighbor as thyself."
I gave my consent to my son, who was yet a minor, that he should enlist in the United States army; I thought it was his duty, and I gave him my advice to fulfill his duty as a good citizen, and he has done so. At the same time I taught him also to observe the Sabbath on Saturday, when it would not hinder him from fulfilling his duty in the army. Now I do not want that he shall be dragged either to the stake or the church to observe the Sunday as a Sabbath. Your Excellency will observe in this my writing that I am not very well versed in the English language, and if there should be found a word which is not right, pardon it, and never such a word shall be construed so as if I would offend your Excellency or the people; for I love my country, the Constitution, and the Union, and I try to be always a loyal citizen.
I remain, respectfully, your most obedient servant and fellow citizen,
