“Every mission constitutes a pledge of duty. Every man is bound to consecrate his every faculty to its fulfilment. He will derive his rule of action from the profound conviction of that duty.”

Famous signal to the British fleet before the battle of Trafalgar, as quoted in Life of Nelson, Ch. 9; Initially dictated as: "England confides that every man shall do his duty." The signaller pointed out that "expects" was in the signals alphabet, but "confides" was not and so had to be spelt out, taking longer, and Nelson agreed to the change.
Variant:
England expects every officer and man to do his duty this day.

Deeds Rather Than Words (1963)
Context: Every person has his own ideas of the act of praying for God's guidance, tolerance, and mercy to fulfill his duties and responsibilities. My own concept of prayer is not as a plea for special favors nor as a quick palliation for wrongs knowingly committed. A prayer, it seems to me, implies a promise as well as a request; at the highest level, prayer not only is a supplication for strength and guidance, but also becomes an affirmation of life and thus a reverent praise of God.

The Saviors of God (1923)
Context: Every man has his own circle composed of trees, animals, men, ideas, and he is in duty bound to save this circle. He, and no one else. If he does not save it, he cannot be saved.
These are the labors each man is given and is in duty bound to complete before he dies. He may not otherwise be saved. For his own soul is scattered and enslaved in these things about him, in trees, in animals, in men, in ideas, and it is his own soul he saves by completing these labors.

1780s, Memorial and Remonstrance Against Religious Assessments (1785)
Context: We hold it for a fundamental and undeniable truth, “that Religion or the duty which we owe to our Creator and the Manner of discharging it, can be directed only by reason and conviction, not by force or violence.” The Religion then of every man must be left to the conviction and conscience of every man; and it is the right of every man to exercise it as these may dictate. This right is in its nature an unalienable right. It is unalienable; because the opinions of men, depending only on the evidence contemplated by their own minds, cannot follow the dictates of other men: It is unalienable also; because what is here a right towards men, is a duty towards the Creator. It is the duty of every man to render to the Creator such homage, and such only, as he believes to be acceptable to him. This duty is precedent both in order of time and degree of obligation, to the claims of Civil Society. Before any man can be considered as a member of Civil Society, he must be considered as a subject of the Governor of the Universe: And if a member of Civil Society, who enters into any subordinate Association, must always do it with a reservation of his duty to the general authority; much more must every man who becomes a member of any particular Civil Society, do it with a saving of his allegiance to the Universal Sovereign. We maintain therefore that in matters of Religion, no man’s right is abridged by the institution of Civil Society, and that Religion is wholly exempt from its cognizance. True it is, that no other rule exists, by which any question which may divide a Society, can be ultimately determined, but the will of the majority; but it is also true, that the majority may trespass on the rights of the minority.
