1. There is but one only, living, and true God: who is infinite in being and perfection, a most pure spirit, invisible, without body, parts, or passions, immutable, immense, eternal, incomprehensible, almighty, most wise, most holy, most free, most absolute, working all things according to the counsel of His own immutable and most righteous will, for His own glory; most loving, gracious, merciful, long-suffering, abundant in goodness and truth, forgiving iniquity, transgression, and sin; the rewarder of them that diligently seek Him; and withal, most just and terrible in His judgments, hating all sin, and who will by no means clear the guilty.

2. God hath all life, glory, goodness, blessedness, in and of Himself; and is alone in and unto Himself all-sufficient, not standing in need of any creatures which He hath made, nor deriving any glory from them, but only manifesting His own glory in, by, unto, and upon them: He is the alone fountain of all being, of whom, through whom, and to whom are all things; and hath most sovereign dominion over them, to do by them, for them, or upon them whatsoever Himself pleaseth. In His sight all things are open and manifest; His knowledge is infinite, infallible, and independent upon the creature, so as nothing is to Him contingent, or uncertain. He is most holy in all His counsels, in all His works, and in all His commands. To Him is due from angels and men, and every other creature, whatsoever worship, service or obedience He is pleased to require of them.

3. In the unity of the Godhead there be three persons, of one substance, power, and eternity; God the Father, God the Son, and God the Holy Ghost. The Father is of none, neither begotten, nor proceeding: the Son is eternally begotten of the Father: the Holy Ghost eternally proceeding from the Father and the Son.

- Begotten and proceeding
- Words for the Son’s and Spirit’s eternal relationships within God; they do not mean being created or starting to exist.
WCF 2.1 · There is one living God
There is only one true God. He is Spirit, without a body or parts, and never changes. He has no beginning or end, knows perfectly, and can do all his holy will. We cannot fully understand him. His love and mercy are perfect, and he is never controlled by changing creaturely moods. He forgives sin, judges justly, and never treats evil as harmless.
Deuteronomy 6:4; 1 Corinthians 8:4; 1 Thessalonians 1:9.
Why is it comforting that God never changes?
WCF 2.2 · God does not need us
God has life, goodness, and joy in himself. He did not create because he lacked something. Everything depends on him, but he depends on nothing he made. He knows everything perfectly, including our thoughts. All he does is holy. We owe him the worship and obedience he requires.
John 5:26; Acts 7:2; Psalm 119:68.
Who depends on whom: God on us, or us on God?
WCF 2.3 · Father, Son, and Holy Spirit
The one God is three distinct persons: the Father, the Son, and the Holy Spirit. Each is fully God, with the same divine nature, power, and eternity. They are not three gods. The Son is eternally begotten of the Father; the Spirit eternally proceeds from the Father and Son. These relationships have no beginning and do not mean anyone was created.
Matthew 3:16–17; Matthew 28:19; 2 Corinthians 13:14.
How can we confess one God while naming three persons?
