Just thought I’d note that apropos my response to Dennis Prager.
Prager wrote that “for all of American history, Jews elected to public office have taken their oath on the Bible, even though they do not believe in the New Testament,” and I realize that a Justice isn’t an elected official. Nonetheless, Justices and elected officials are bound by the same oath-or-affirmation provision of the Constitution, and all federal officeholders are equally protected by the Religious Test Clause.
