The baseline law
Title VII of the Civil Rights Act of 1964 makes it illegal for most employers with 15 or more workers to discriminate in hiring, firing, pay, or promotion based on race, color, religion, sex, or national origin. Later statutes and court decisions extended similar protections to cover age, disability, and — under the Supreme Court's 2020 Bostock ruling — sexual orientation and gender identity as forms of sex discrimination.
The statutory exemption for religious employers
When Congress wrote Title VII, it included a carve-out: religious corporations, associations, educational institutions, and societies may favor members of their own faith in employment decisions. That means a Catholic parish, a Jewish day school, or a Muslim charity can lawfully require employees to share its religion. The exemption applies to religion specifically; it does not, on its face, authorize discrimination based on race, sex, or national origin.
The 'ministerial exception'
Beyond the statute, courts have read the First Amendment to bar the government from interfering in a religious group's choice of its ministers. In Hosanna-Tabor Evangelical Lutheran Church and School v. EEOC (2012), the Supreme Court unanimously recognized this 'ministerial exception,' ruling that a teacher who had been designated a 'called' minister could not bring a disability discrimination suit against her church-run school.
How far the exception reaches
In Our Lady of Guadalupe School v. Morrissey-Berru (2020), the Court extended the exception 7-2 to two lay teachers at Catholic schools whose duties included religious instruction, even though neither carried a formal ministerial title. The majority said courts should look at the substance of an employee's role, not just the label, in deciding whether the exception applies.
The case for broader exemptions
Supporters argue that the Free Exercise Clause protects religious communities' ability to define their own beliefs and choose who teaches and represents them, and that the Establishment Clause forbids the government from second-guessing those internal judgments. They contend that without robust exemptions, faith-based schools, charities, and houses of worship could be forced to hire people whose conduct or beliefs conflict with the organization's mission.
The case for narrower exemptions
Critics argue that broad exemptions can leave workers without legal recourse against discrimination based on sex, sexual orientation, gender identity, race, or disability — particularly in large religiously affiliated hospitals, universities, and social service agencies that employ many non-clergy staff and often receive public funding. They say the line between 'religious' and 'secular' duties has become blurry, and that expansive readings of the ministerial exception can sweep in employees whose jobs are not primarily about faith.
What's still contested
Open questions include how to handle employees whose religious duties are minor or disputed, whether exemptions should extend to organizations that take government contracts or grants, and how the ministerial exception interacts with Bostock's protections for LGBTQ workers. Lower courts continue to apply these rulings case by case, and Congress periodically considers legislation — such as the Equality Act and the Do No Harm Act — that would adjust the balance in different directions.
