The correct answer is The words emphasize the importance of the Declaration's text by equating it with the founding document of a religion

This occurs as he uses terms such as "sacred obligation" or "creed" (faith).

According to this, the correct answer is "The words emphasize the importance of the Declaration's text by equating it with the founding document of a religion ."
