“..the FOUNDERS did not intend for any religious test to be applied.”
There was a religious test in almost every state for public office, and it required that an oath be taken somewhat along the lines of believing in Jesus Christ and the Old and New Testament as divine revelation. Each state had a state sponsored Christian denomination religion.
The “no religious test” at the Federal level was for denominations; “no denomination religious test.” The first amendment was to make sure that the federal government wouldn’t usurp any specific state sponsored Christian denomination and make a national sponsored Christian denomination. The founders didn’t want Christian religious wars over denominations similar to what wreaked havoc on Europe and what was the reason for migration to the New World.
The no federal religious test was to make sure that no specific Christian denomination would be supported, and all Christian denominations would be equally treated. But it was always Christian. At that time, nothing was even considered another religion. There was only the Christian religion with many denominations.
So you would exclude a Jew?
A Scientologist?
Who else? A Mormon? A Seventh-Day Adventist . . . oh, wait. According to some denominations, they aren't Christians.
