1.1.1.18. God is infinite perfection and goodness.

"There is nothing lacking in God. There is no division in Him, no distension of Him, no limit to Him. He is an infinite ocean of perfection, and He possesses it all at once in the eternal instant of His infinite life. There is no unrealized potential in God; He is pure act. And therefore He is infinitely and completely good. In the unspeakable happiness of the trinitarian life, God’s infinite perfection is known, expressed, loved, and given between three persons who are each the one God."
