“Rex non potest peccare” is a Latin phrase that means “the king cannot sin.” This phrase represents the concept of the divine right of kings. It suggests that monarchs obtain their authority directly from a higher power like God. Therefore, their actions are inherently righteous and beyond reproach. This idea has historically been used to justify absolute monarchy. It has also discouraged opposition or rebellion against the ruler. However, it is important to note that this concept has been heavily debated and criticized throughout history. This is especially true during periods of political unrest and the emergence of democratic ideals.
