[Politely but firmly, Washington indicates in this letter some of the moral conditions of citizenship.]
Government being, among other purposes, instituted to protect the persons and consciences of men from oppression, it certainly is the duty of rulers, not only to abstain from it themselves, but, according to their stations, to prevent it in others.
The liberty enjoyed by the people of these states of worshipping Almighty God agreeably to their consciences, is not only among the choicest of their blessings, but also of their rights. While men perform their social duties faithfully, they do all that society or the state can with propriety demand or expect; and remain responsible only to their Maker for their religion, or modes of faith, which they may prefer or profess.
Your principles and conduct are well known to me; and it is doing the people called Quakers no more than justice to say, that (except their declining to share with others the burden of the common defense) there is no denomination among us, who are more exemplary and useful citizens. [Washington is alluding to the Quaker refusal to serve in the armed forces.]
I assure you very explicitly, that in my opinion the conscientious scruples of all men should be treated with great delicacy and tenderness; and it is my wish and desire, that the laws may always be as extensively accommodated to them, as a due regard to the protection and essential interests of the nation may justify and permit.
