The phrase came to be adopted as the Calvinist motto, and was subsequently adopted as the motto of the entire Protestant Reformation.^[2] It is used by John Calvin's adopted city of Geneva, Switzerland on their coins. As a mark of its role in the Calvinist movement, the motto is engraved on the Reformation Wall, in Geneva, and the Huguenot Monument, in Franschhoek, South Africa.
