The Latin phrase is Vox populi, vox Dei. It translates to "the voice of the people is the voice of God" and is often used to express the idea that public opinion or the will of the people carries ultimate authority or truth in democratic contexts. Key points

• Origin and usage: The expression comes from Latin and has medieval associations; it has historically been used to comment on the weight of public opinion within governance and community decision-making.

• Variants and scope: The full form is vox populi, vox Dei; sometimes only vox populi is quoted, and it’s frequently invoked to emphasize the importance of popular sentiment in political or moral judgments.

• Modern reception: The phrase appears in discussions about democracy, public opinion, and the balance between rulers and the governed, and it is sometimes invoked in cultural works and discussions about authority.
