The reason secularists continue to seek removal of public expressions of faith such as “National Day of Prayer” or “In God We Trust” is because they have turned the First amendment on its head to mean no public expressions of faith whereas historically it actually protected that expression.
Historically, the First Amendment limited only the federal government with wording like “Congress shall make no law….” Of course today, secularists seek to label any public expression of faith as a federal endorsement of faith.
So here is a simple way to distinguish a law from a proclamation of accommodation. A law requires one to do something or not to do something and violating such law is punishable by the government. In contrast, a proclamation or recitation does not require anyone to participate, and if they choose not to there is no legal punishment.
