In which attributes is God unchangeable according to the teaching?

The teaching of the Westminster Shorter Catechism clearly articulates that God is unchangeable in several essential attributes: His being, wisdom, power, holiness, justice, goodness, and truth. This perspective is foundational in Reformed theology, emphasizing that God is consistent and constant in His nature and character throughout all times and circumstances.

God's being refers to His existence and essence, which are not subject to change. Similarly, His wisdom remains perfect and unchanging, allowing Him to govern the universe with total knowledge and insight. The attribute of power indicates that God’s ability to act is without limit and is not influenced by external factors. Holiness signifies His separation from sin and moral perfection, which is eternally unwavering.

Justice reflects God's righteousness in His actions towards creation, goodness expresses His benevolent nature, and truth signifies that God is always truthful, with no possibility of deception or falsehood. Each of these attributes reassures believers that they can trust God completely since He does not evolve or alter His nature based on human circumstances or decisions.

This comprehensive understanding of God's unchangeability in His fundamental attributes is critical for grasping the broader implications of His divine nature as presented in the Catechism.
