Begin with attribution. A religious message written and displayed by a city as its own statement raises an Establishment Clause question. The same message presented by a private speaker in a public forum open to many viewpoints remains private expression. Location alone does not answer the question. A prayer led by a public-school teacher during class uses official authority; a student who quietly prays during lunch ordinarily speaks for the student. Courts examine who selected the message, who controls the setting, whether listeners would face practical pressure to join, and whether comparable private expression is permitted.

Public services and benefits illustrate the same distinction. Providing police protection, street access, or emergency services to a synagogue on the same terms as other property does not establish religion. A neutral tuition or scholarship program may allow families to choose a religious school through independent private decisions. By contrast, a direct governmental instruction to worship or a benefit reserved for one denomination would use public power to advance religion. Excluding a qualified participant simply because it is religious can create a Free Exercise problem rather than solve an Establishment Clause problem.

Replace the slogan with four concrete questions. Who is speaking or acting: government or a private person? Does the government coerce participation or adherence? Does the rule favor or disfavor religion compared with relevant secular activity? Does any public benefit reach a religious organization through neutral criteria and genuine private choice? Those questions explain why both official sponsorship and official hostility can be unconstitutional. Exam distinction: separation limits governmental establishment without requiring government to isolate or disadvantage private faith.
