Which quality is NOT attributed to God in the Westminster Shorter Catechism?

The quality that is designated as "Changeable" is the correct answer because it opposes the fundamental understanding of God's nature as presented in the Westminster Shorter Catechism. The catechism teaches that God is immutable, meaning He does not change. This aspect of God’s nature emphasizes His perfection and consistency, reinforcing that His character, purposes, and promises remain constant throughout time.

In contrast, the other qualities listed such as "Infinite," "Eternal," and "Unchangeable," highlight key attributes of God that affirm His greatness and sovereignty. "Infinite" signifies that God has no limits, "Eternal" indicates that He exists outside of time and has no beginning or end, and "Unchangeable" reaffirms that God's essence and will do not fluctuate. Each of these qualities reflects a deep theological understanding of God that is central to Reformed theology and outlined in the Westminster Shorter Catechism.
