Quotes

 * Our sentiments are uniformly on the side of religious liberty: that Religion is at all times and places a matter between God and individuals, that no man ought to suffer in name, person, or effects on account of his religious opinions, that the legitimate power of civil government extends no further than to punish the man who works ill to his neighbor. But sir, our constitution of government is not specific. Our ancient charter, together with the laws made coincident therewith, were adapted as the basis of our government at the time of our revolution. And such has been our laws and usages, and such still are, that Religion is considered as the first object of Legislation, and therefore what religious privileges we enjoy (as a minor part of the State) we enjoy as favors granted, and not as inalienable rights. And these favors we receive at the expense of such degrading acknowledgments, as are inconsistent with the rights of freemen. It is not to be wondered at therefore, if those who seek after power and gain, under the pretense of government and Religion, should reproach their fellow men, should reproach their Chief Magistrate, as an enemy of religion, law, and good order, because he will not, dares not, assume the prerogative of Jehovah and make laws to govern the Kingdom of Christ.
 * Letter from the Danbury Baptists to Thomas Jefferson, October 7, 1801


 * Believing with you that religion is a matter which lies solely between Man & his God, that he owes account to none other for his faith or his worship, that the legitimate powers of government reach actions only, & not opinions, I contemplate with sovereign reverence that act of the whole American people which declared that their legislature should ʺmake no law respecting an establishment of religion, or prohibiting the free exercise thereof,ʺ thus building a wall of separation between Church & State. Adhering to this expression of the supreme will of the nation in behalf of the rights of conscience, I shall see with sincere satisfaction the progress of those sentiments which tend to restore to man all his natural rights, convinced he has no natural right in opposition to his social duties.
 * Letter from Thomas Jefferson to the Danbury Baptists, January 1, 1802


 * The State may not establish a "religion of secularism" in the sense of affirmatively opposing or showing hostility to religion, thus "preferring those who believe in no religion over those who do believe." ... In addition, it might well be said that one’s education is not complete without a study of comparative religion or the history of religion and its relationship to the advancement of civilization. It certainly may be said that the Bible is worthy of study for its literary and historic qualities. Nothing we have said here indicates that such study of the Bible or of religion, when presented objectively as part of a secular program of education, may not be effected consistently with the First Amendment.
 * Supreme Court of the United States, Abington School District v. Schempp, 374 U.S. 203 (1963)


 * Under our system, the choice has been made that government is to be entirely excluded from the area of religious instruction, and churches excluded from the affairs of government. The Constitution decrees that religion must be a private matter for the individual, the family, and the institutions of private choice, and that, while some involvement and entanglement are inevitable, lines must be drawn.
