How is sin defined in the context of the catechism?

In the context of the Westminster Shorter Catechism, sin is defined as "any want of conformity to or transgression of God’s law." This definition emphasizes that sin encompasses both failing to meet the standards set forth by God and actively going against those standards.

The notion of conformity is crucial; it highlights that sin is not merely about actions that are overtly wrong but also includes the omission of good that God requires. This dual definition allows for a comprehensive understanding of sin as it addresses both the heart and behavior of an individual. God's law is central to this understanding, serving as the standard by which all human actions and thoughts are measured.

This definition aligns with the biblical understanding of sin as articulated in various scriptures, including 1 John 3:4, which states that sin is lawlessness. By recognizing that sin is both a failure to conform to God’s law and an act of transgression against it, this definition encapsulates the complete nature of sin in the theological framework provided by the catechism.
