The Trinity

The doctrine of the Trinity is not a distant theological puzzle but the very shape of the gospel. It teaches that the one true God exists eternally as three persons—Father, Son, and Holy Spirit—and that each person is fully God, yet there are not three Gods but one. This matters because salvation itself is a work of the triune God. If we misunderstand the Trinity, we will misunderstand who saves us, how we are saved, and whom we worship. The authors gathered here press this home: the Father, the Son, and the Holy Spirit cooperate in redemption, and true faith must rest on all three.

The Father appoints the Son as propitiation Charles Spurgeon insists that the work of atonement began in the Father's will. He argues that God the Father, in divine wisdom and sovereignty, chose and appointed Christ the Son to be the propitiation for sins (Romans 3:25). This means the cross was not an accident or merely the act of a loving Son overcoming a reluctant Father. It was the Father's own plan. Spurgeon's emphasis guards against any view that sets the Father against the Son in the work of redemption. The Father is not a distant judge who must be persuaded by the Son; he is the one who sends the Son.

Faith must not overlook the Father Spurgeon repeatedly warns against a one-sided faith that trusts Jesus apart from the Father. He says true saving faith trusts in God the Father as the one who raised Jesus from the dead, not in Jesus apart from the Father (Romans 4:24–25). This is a striking pastoral point. Many believers gladly trust Christ but rarely think of the Father as the object of their faith. Spurgeon corrects this. The resurrection was the Father's act upon the Son, and saving faith must include that reality. He adds that true faith trusts God the Father and Jesus Christ together, not one apart from the other (Romans 4:24).

The Father and Son act together in redemption Spurgeon does not allow the Father and the Son to be separated in the work of salvation. He states plainly that the Father and the Son acted together in the work of redemption, so the Father must not be overlooked in salvation (Romans 4:24). This is not a minor point of theological tidiness. If the Father is overlooked, the gospel itself is distorted. The Father gave his Son to suffer, so in a real sense God the Father is our Savior along with Jesus Christ (Romans 4:25). Spurgeon is careful: he does not say the Father suffered or that the Father became incarnate, but he does say the Father's giving of the Son is so central that the Father is rightly called Savior. This is a strong emphasis on the unity of the divine work.

The whole Trinity cooperates in salvation Spurgeon broadens the point to include the Holy Spirit. He declares that the whole Trinity—Father, Son, and Holy Spirit—cooperates in salvation, and all three must be trusted and praised (Romans 4:24). Here the doctrine of the Trinity becomes doxology. Salvation is not a transaction between the sinner and one divine person only. It is the work of the triune God. The Father plans and sends, the Son accomplishes propitiation and rises, the Spirit applies the work to the heart. To trust one person while ignoring the others is to have an incomplete faith. Spurgeon's emphasis is practical: if all three persons save, then all three must be trusted and praised.

The Trinity humbles human pride Jonathan Edwards takes the doctrine in a different but complementary direction. He argues that the doctrine of the Trinity was revealed so that we would see our salvation depends wholly on God and not on ourselves (1 Corinthians 1:29–31). Edwards is concerned with human boasting. If salvation were the work of only one divine person, or if it depended partly on human effort, there might be room for pride. But because the Father elects, the Son redeems, and the Spirit applies, every aspect of salvation is divine. The Trinity leaves no place for self-congratulation. Edwards' emphasis is more theological and polemical than Spurgeon's, but the conclusion is the same: the triune God alone saves.

The Trinity shapes Christian unity and worship Matthew Henry adds a corporate and liturgical dimension. He says God must be glorified as the Father of our Lord Jesus Christ, according to the gospel and with an eye to Christ (Romans 15:6). For Henry, right worship is Trinitarian worship. We do not worship a generic God but the Father of our Lord Jesus Christ. He also connects the Trinity to the unity of believers. The unity of Christians glorifies God as the Father of our Lord Jesus Christ because it represents the oneness between the Father and the Son (Romans 15:6, John 17:21). Christian unity is not merely organizational; it reflects the eternal unity of the Father and the Son. Finally, Henry insists that the wisdom ascribed to God belongs to Father, Son, and Holy Spirit, the three persons of the one God (Romans 16:27). The wisdom that saves is the wisdom of the triune God.

At any rate, there was this choice between the Father, the Son, and the Holy Spirit; the Divine Wisdom conjoined with Divine Sovereignty, and chose and appointed and determined that Christ Jesus, the Second of the Mysterious Three, should be the Propitiation for our sins Charles Spurgeon, sermon “Christ Set Forth As A Propitiation” True faith is of this character—"We believe on Him that raised up Jesus, our Lord, from the dead; who was delivered for our offenses, and was raised, again, for our justification Charles Spurgeon, sermon “The Two Pillars Of Salvation” Some overlook the Father. They speak of Jesus as though we were indebted to Him and to Him, only, for our salvation. We are immeasurably indebted to Him, blessed be His name! But Jesus does not save without the Father, or apart from the Father, or against the Father's will Charles Spurgeon, sermon “The Two Pillars Of Salvation” I might say, in a certain sense, that it was God the Father who suffered for us, for He gave His Son, whom He loved, to suffer on our behalf. He gave up the darling of His heart and, in the Person of His Son, He became our Savior Charles Spurgeon, sermon “The Two Pillars Of Salvation” It is not the Father without the Son who saves, nor the Son without the Father—nor these two without the Divine and ever-to-be-blessed Holy Spirit! It needs the whole Trinity to make a Christian! And the whole Trinity, co-operating in a Divine Unity, must be praised and adored for our salvation Charles Spurgeon, sermon “The Two Pillars Of Salvation” So, then, we cannot truly trust to Jesus apart from the Father. To come back to the point on which I have already spoken to you—to try to drive that nail home and even to clinch it—we do not look to Jesus apart from the Father, any more than we look to the Father apart from Jesus Charles Spurgeon, sermon “The Two Pillars Of Salvation” It seems to have been very much on this account, that it was requisite the doctrine of the Trinity itself should be revealed to us; that by a discovery of the concern of the several divine persons in the great affair of our salvation, we might the better understand and see how all our dependence in this affair is on God, and our sufficiency all in him, and not in ourselves Jonathan Edwards, “Justification by Faith Alone” God must be glorified as he has now revealed himself in the face of Jesus Christ, according to the rules of the gospel, and with an eye to Christ, in whom he is our Father Matthew Henry, “Exposition of the Old and New Testaments” The unity of Christians glorifies God as the Father of our Lord Jesus Christ, because it is a kind of counter-part or representation of the oneness that is between the Father and the Son Matthew Henry, “Exposition of the Old and New Testaments” He is only wise; not the Father only wise, exclusive of the Son, but Father, Son, and Holy Ghost, three persons and one God, only wise, compared with the creatures Matthew Henry, “Exposition of the Old and New Testaments”

These authors agree on the central point: the Trinity is essential to the gospel. Spurgeon stresses the cooperation of Father and Son in redemption and the need to trust both. Edwards stresses the humbling effect of the doctrine. Henry stresses worship and unity. Their differences are matters of emphasis, not contradiction. Spurgeon is the most direct about the danger of overlooking the Father. Edwards is the most focused on human pride. Henry is the most focused on the church's common life. Together they show that the Trinity is not a speculative doctrine but the foundation of saving faith, humble worship, and Christian unity.
