Amendment I (Religion)
Document 65
Thomas Jefferson to Albert Gallatin
16 June 1817Works 12:73Three of our papers have presented us the copy of an act of the legislature of New York, which, if it has really passed, will carry us back to the times of the darkest bigotry and barbarism, to find a parallel. Its purport is, that all those who shall hereafter join in communion with the religious sect of Shaking Quakers, shall be deemed civilly dead, their marriages dissolved, and all their children and property taken out of their hands. This act being published nakedly in the papers, without the usual signatures, or any history of the circumstances of its passage, I am not without a hope it may have been a mere abortive attempt. It contrasts singularly with a cotemporary vote of the Pennsylvania legislature, who, on a proposition to make the belief in God a necessary qualification for office, rejected it by a great majority, although assuredly there was not a single atheist in their body. And you remember to have heard, that when the act for religious freedom was before the Virginia Assembly, a motion to insert the name of Jesus Christ before the phrase, "the author of our holy religion," which stood in the bill, was rejected, although that was the creed of a great majority of them.
