Freedom of religion

The Maryland Toleration Act secured religious liberty in the English colony of Maryland. Similar laws were passed in the Rhode Island and Providence Plantations, Connecticut and Pennsylvania. These laws stood in direct contrast with the Puritan theocratic rule in the Plymouth and Massachusetts Bay colonies.^[25]

The United States federal government was the first national government to have no official state-endorsed religion.^[26] However, some states had established religions in some form until the 1830s.

Modeling the provisions concerning religion within the Virginia Statute for Religious Freedom, the framers of the Constitution rejected any religious test for office, and the First Amendment specifically denied the federal government any power to enact any law respecting either an establishment of religion or prohibiting its free exercise, thus protecting any religious organization, institution, or denomination from government interference. The decision was mainly influenced by European Rationalist and Protestant ideals, but was also a consequence of the pragmatic concerns of minority religious groups and small states that did not want to be under the power or influence of a national religion that did not represent them.^[27]
