Religious Freedom Under the Constitution

The First Amendment of the Constitution contains two clauses related to religious freedom: the Establishment Clause and the Free Exercise Clause. The Establishment Clause prevents the government from making a law related to "an establishment of religion," which means that it cannot endorse a certain religion or become entangled in religious activities. This essentially describes the separation of church and state that is fundamental to American democracy. Meanwhile, the Free Exercise Clause prevents the government from prohibiting the free exercise of individual religious beliefs. It also provides some protection for religious practices.

These clauses often overlap, but they also may conflict. For example, a government entity may violate the Free Exercise Clause if it does not provide some basic services to religious institutions. On the other hand, a government entity may violate the Establishment Clause if it provides too many services to religious institutions. The government thus is tasked with striking a balance between the prohibitions in these clauses, which is not always straightforward.

What Are Religious Beliefs?

For First Amendment purposes, religious beliefs do not need to fall within the structure of an organized religion, nor do they need to involve a belief in a supreme being. Beliefs will be considered religious if they are sincerely held and if they function as a religion for that person.

How the Establishment Clause Protects Religious Freedom

The Supreme Court generally has endorsed an interpretation of the Establishment Clause that requires the government to refrain from favoring religion over secularism, and from favoring any religion over any other religion. The Court traditionally applied a test known as the Lemon test (from its decision in Lemon v. Kurtzman) when deciding whether a government action violates the Establishment Clause. This test consists of three components:

If a law passed each of these three hurdles, the Court would find that it did not violate the Establishment Clause. However, not every Establishment Clause decision adhered strictly to the Lemon test, and the Court recently indicated that it has abandoned this test for a more fluid approach. Cases often rely heavily on their specific facts. For example, the government can provide buses to take children to religious schools, but they cannot provide buses to take children in religious schools on field trips.

Prayers in Public Schools

Public schools cannot hold daily prayers under the Establishment Clause, nor can they hold regular Bible readings, prayers at school events (even if student-initiated), or moments of silence for meditation. On the other hand, schools must allow student groups or non-school entities that use school property to pursue religious activities on the property. This is based on another First Amendment right, freedom of speech, under which prayer is considered protected expression.

How the Free Exercise Clause Protects Religious Freedom

The Free Exercise Clause prevents the government from targeting certain religious groups or prohibiting certain religious practices. However, the government can prohibit certain conduct in general without creating an exception for people who engage in that conduct for religious reasons. These laws initially needed to pass strict scrutiny. This standard of review requires the government to identify a compelling government interest and prove that the law is necessary to serve that interest. The law must be narrowly tailored and use the least restrictive means to further the government interest.

Most laws do not survive strict scrutiny, and the Supreme Court lightened the burden on the government in Employment Division v. Smith in 1990. In this case, the Court ruled that a law does not violate the Free Exercise Clause if it is generally applicable and was not designed to interfere with religion, regardless of its actual effect on religious practices. Congress responded with the Religious Freedom Restoration Act (RFRA), which provided that the government cannot substantially burden the free exercise of religion, even when enacting a rule of general applicability. (RFRA essentially reinstated strict scrutiny for these laws.) The Supreme Court struck down RFRA as applied to the states, but it remains in effect as applied to the federal government. Over 20 states have enacted their own versions of RFRA as well.

Corporations and Religious Freedom

In Burwell v. Hobby Lobby, the Supreme Court ruled that a privately held corporation could be exempt from a federal law or regulation to which its owners object on religious grounds. (This case involved a regulation under the Affordable Care Act that required employers to provide contraceptive coverage to employees.) The Court applied RFRA in finding that the contraceptive mandate was not the least restrictive means of furthering the government interest. However, the decision was limited to privately held corporations.
