Summary

Expository

The doctrine of the Trinity — one undivided divine essence eternally subsisting as Father, Son, and Holy Spirit — is the indispensable foundation of the Christian's communion with God and of confident, reverent worship.

The doctrine of the Trinity is not a division of the divine essence into three parts, but one infinite and undivided substance eternally subsisting as Father, Son, and Holy Spirit. The confession's language moves deliberately between the oneness and the threeness of God — the Father unbegotten, the Son eternally begotten, the Holy Spirit proceeding from both — holding the unity and the distinction together without confusion. This doctrine is not speculative theology but the very foundation of the Christian's communion with God and the ground of confident, joyful worship.

Key quotes

It's not that the Father is 33 and a third, the Son 33 and a third, and the Holy Spirit 33 and a third, but the language of the oneness of substance is reiterated three times.
Not a chopped up or divided deity, but each having the whole divine essence, yet the essence undivided.
One infinite, eternal, and divine being who eternally exists as Father, Son, and Holy Spirit, and who has condescended to, by His grace, call us from deadness to life to worship Him and enjoy Him fully.

Applications

  1. Approach the Father, Son, and Holy Spirit in worship with reverence, humility, and joy, grounded in the reality of who God is.
  2. Do not treat the doctrine of the Trinity as speculative or burdensome labor — receive it as the foundation of your communion with God.
  3. Rest your dependence on God not merely on His power but on the triune nature that grounds His relation to His people.

Questions this sermon answers

Is God divided into three equal parts in the Trinity?

No. Each of the three persons — Father, Son, and Holy Spirit — possesses the whole divine essence, not a third of it; the essence is undivided.

What makes the Father, Son, and Holy Spirit distinct persons?

They are distinguished by personal properties: the Father is of none, neither begotten nor proceeding; the Son is eternally begotten of the Father; and the Holy Spirit proceeds from the Father and the Son.

Why does the doctrine of the Trinity matter for everyday Christian life?

It is the very foundation of the believer's communion with God and the basis on which the Christian can comfortably and joyfully depend on the One who upholds all things.

The Triunity of God

the doctrine of God closes with the blessed reality that our God is triune, and that this triunity isn't a divine essence, isn't a God that's parsed up into three parts. It's not that the Father is 33 and a third, the Son 33 and a third, and the Holy Spirit 33 and a third, but the language of the oneness of substance is reiterated three times. It's very Trinitarian in its declaration of the oneness and the unity, the substantial unity of God. And then it's also triune in thrice declaring the triunity of God.

Notice, in this divine and infinite being, so the oneness of God is here first stated, there are three subsistences, the Father, Word, or Son, and the Holy Spirit. Now back to the oneness of one substance, power and eternity. Now notice, not a chopped up or divided deity, but each having the whole divine essence, yet the essence undivided. And now from the one back to the three.

The Father is of none, neither begotten nor proceeding. The Son is eternally begotten of the Father, the Holy Spirit proceeding from the Father and the Son. And then back to the One, all-infinite, without beginning, therefore but one God, who is not to be divided in nature and being. Back to the Three, but distinguished. by several peculiar relative properties and personal relations, which doctrine of the Trinity is the foundation of all our communion with God and comfortable dependence on Him."

Foundation of Communion with God

What is the importance of the doctrine of God? Why do we spend time on it as Christians? Why do we spend time, and hopefully it doesn't seem like a weariness or extra labor unjustly applied to a subject, why do we spend so much time on the doctrine of God? Because it is the very foundation of our communion with Father, Son, and Holy Spirit, and it's the very foundation that we can, as His worshipers, comfortably depend upon the One who upholds us, who gives us life, breath, and all things, who causes us to reverently humbly and joyfully approach Him in worship.

What a glorious God that we have. One infinite, eternal, and divine being who eternally exists as Father, Son, and Holy Spirit, and who has condescended to, by His grace, call us from deadness to life to worship Him and enjoy Him fully.
