Final answer:
Samuel F. B. Morse suggested that the natural effect of the Protestant faith is a form of government that counters factionalism and promotes democratic institutions.
Step-by-step explanation:
According to "Imminent Dangers to the Free Institutions of the United States" by Samuel F. B. Morse, the form of government that Morse claims to be the natural effect of the Protestant faith is one that provides the proper antidote for the diseases of faction. Morse emphasized that the Protestant faith led to the development of democratic institutions. He feared that sectarian strife from various religious groups and the lack of a uniform Protestant creed could threaten the stability and unity of the nation.
