Denise Spellberg notes that on July 30th, 1788 Muslims “became symbolically embroiled in the definition of what it meant to be American citizens.” Speaking in light of who might one day occupy the White House, William Lancaster, a delegate to the North Carolina convention, stated:
“But let us remember that we form a government for millions not yet in existence. I have not the art of divination. In the course of four or five hundred years, I do not know how it will work. This is most certain, that [Catholics] may occupy that chair, and [Muslims] may take it. I see nothing against it.”
Spellberg sheds further light on Lancaster’s passage:
“Lancaster asserted these future fears of a “certain” Catholic or Muslim president on July 30, 1788 as part of a day-long debate on the Constitution’s Article VI, section 3: “… no religious Test shall ever be required as a Qualification to any Office or public Trust under the United States.” His views are preserved as the final utterance in the most detailed attack on – and defense of – a uniquely American ideal of religious pluralism, one that included Muslims at the founding.”
Here is the official text from Lancaster.
