How are God’s divine characteristics related to His divine being?

Q161 · Faith in God and Our Knowledge of Him

We can identify some divine characteristics as pertaining exclusively to His divine being, but not to the creation. God alone is self-existent, absolutely perfect, transcends space and time, unseen, not derived from any another existent, and without beginning or end. He is the same yesterday, today, and tomorrow; without change, and perfect in all His attributes, for His characteristics do not stand in need of any created thing in order to be manifest.
