They treat the Constitution like they do their bible.

They don’t read it.

If they do read it, they just read the bits they agree with.

If they read the parts that don’t fit their desired narrative, they engage in mental gymnastics to reinterpret what was written to fit their desires.

Edit:

Jefferson's reply did not address their concerns about problems with state establishment of religion — only of establishment on the national level. The letter contains the phrase "wall of separation between church and state," which led to the short-hand for the Establishment Clause that we use today: "Separation of church and state."

Which led to the Establishment Clause…

Congress shall make no law respecting an establishment of religion...

And also The point of Article 6 wherein no religious test is to be given to hold office.

Better?
