Except for the Christian Religions and Judaism, all the rest are 3 dollar bills.
Maybe, but the plain words of the Constitution do not state that the right to the free exercise of Chrisitianity or Judaism are protected. The right to free exercise of RELIGION is what is protected.
You REALLY don’t want government to be the judge of what is true and false religion. Don’t forget, laws can change. The religious makeup of the population at large can change. What if atheists, for instance, become politically dominant. What if the atheist-dominated government decides that ALL religions are false and effectively repeals the First Amendment?
Admittedly, such hypotheticals may seem implausible, but do you really want government to have the power to determine religious truth? The only real solution is the one that the Founders gave us - the plain text of the First Amendment. This plainly protects ALL religions, whether or not they are true or false ones.
