This is an opinion, and we label it as one rather than rating it true or false. The point of setting it down is to place the strongest form of the argument next to the document it would have to defeat.
Start with that strongest form, fairly stated. There is a long, mainstream tradition of arguing that a nation's laws and public culture are shaped by the moral and religious traditions of most of its people, and that citizens formed by faith make better self-governance possible. Held that way, as a claim about culture and character, the position is an ordinary one in a democracy and does not bar anyone from anything. A reader can disagree with it and still recognize it as a normal argument about the sources of civic virtue.
That is not the argument on the table here. Joel Webbon, who runs Right Response Ministries and has roughly 108,000 followers on X, does not stop at culture [1]. He says leadership "belongs to Christians," and then he draws the line by name: "It's not for Hindus. It's not for Muslims," and, in the same breath, "not for Jews" [1]. The move from a majority's cultural influence to a bar on named minorities holding power is the whole distance between the steel-manned version and the one he is actually making.
He goes further than exclusion. Webbon advocates that men "forcefully take away from the people that which is their detriment," and frames the project as a takeover, with 2032 as a target [1]. The language of force, aimed at a specific timeline, is what separates a debating position from a program.
Now the record it runs into, in the founding text's own words. Article VI of the Constitution provides that officeholders "shall be bound by Oath or Affirmation, to support this Constitution; but no religious Test shall ever be required as a Qualification to any Office or public Trust under the United States" [2]. The clause is not ambiguous, and it is not narrow: no religious test, ever, for any office. A rule that leadership belongs to Christians and not to Jews, Muslims, or Hindus is precisely a religious test for public trust, which Article VI forbids.
The First Amendment closes the other door. "Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof" [3]. Installing one faith as the qualification for governing is an establishment of that religion by another name, the thing the amendment was written to prevent.
There is no verdict to render on the theology, and this desk does not offer one. What can be stated flatly is the legal record. The Constitution the argument would govern under already answers it, in text that predates the argument by more than two centuries: the offices are open regardless of creed, and no one may be made to pass a religious test to hold them.
