What is defined as sin according to the Westminster Shorter Catechism?

The definition of sin according to the Westminster Shorter Catechism is that it is any transgression of the law of God. This definition encompasses not only actions that violate moral standards but also disobedience to God's commands as outlined in scripture. It acknowledges that sin can be both visible actions and internal attitudes or motivations that stray from God's established laws.

This broad definition reflects a theological understanding that sin involves any deviation from God's will, making it inclusive of both moral and ceremonial aspects of the law. In contrast, the other options are too narrow or misrepresent the comprehensive nature of sin by focusing only on specific behaviors or contexts, thus failing to capture the full biblical perspective on what constitutes sin in relation to God’s law.
