Context: We have abundant reason to rejoice, that, in this land, the light of truth and reason has triumphed over the power of bigotry and superstition, and that every person may here worship God according to the dictates of his own heart. In this enlightened age, & in this land of equal liberty, it is our boast, that a man's religious tenets will not forfeit the protection of the laws, nor deprive him of the right of attaining & holding the highest offices that are known in the United States.
Your prayers for my present and future felicity are received with gratitude; and I sincerely wish, Gentlemen, that you may in your social and individual capacities taste those blessings, which a gracious God bestows upon the righteous.

Ten Sermons of Religion (1853), III : Of Justice and the Conscience https://en.wikisource.org/wiki/Ten_Sermons_of_Religion/Of_Justice_and_the_Conscience
Context: Man naturally loves justice, for its own sake, as the natural object of his conscience. As the mind loves truth and beauty, so conscience loves the right; it is true and beautiful to the moral faculties. Conscience rests in justice as an end, as the mind in truth. As truth is the side of God turned towards the intellect, so is justice the side of Him which conscience looks upon. Love of justice is the moral part of piety.

§ 15. Often misquoted as “Religion is the basis and foundation of government.”
