The Trinity

Explain one divine being, three distinct persons, and their united work without modalism or tritheism.

God and His works

Read first

Deuteronomy 4:23-40 · John 1:1-18 · John 14:15-31 · Ephesians 1:3-23

The Trinity is often criticized as though Christians were saying that one person is three persons in the same sense. That would be a contradiction. The actual claim distinguishes who God is from the divine nature the Father, Son, and Holy Spirit share. The vocabulary takes a little work, but confusion is not a reason to replace the teaching with something easier and false.

Read Deuteronomy 4:32-40

32 For ask now of the days that are past, which were before you, since the day that God created man on the earth, and from the one end of the sky to the other, whether there has been anything as great as this thing is, or has been heard like it?
33 Did a people ever hear the voice of God speaking out of the middle of the fire, as you have heard, and live?
34 Or has God tried to go and take a nation for himself from among another nation, by trials, by signs, by wonders, by war, by a mighty hand, by an outstretched arm, and by great terrors, according to all that the LORD your God did for you in Egypt before your eyes?
35 It was shown to you so that you might know that the LORD is God. There is no one else besides him.
36 Out of heaven he made you to hear his voice, that he might instruct you. On earth he made you to see his great fire; and you heard his words out of the middle of the fire.
37 Because he loved your fathers, therefore he chose their offspring after them, and brought you out with his presence, with his great power, out of Egypt;
38 to drive out nations from before you greater and mightier than you, to bring you in, to give you their land for an inheritance, as it is today.
39 Know therefore today, and take it to heart, that the LORD himself is God in heaven above and on the earth beneath. There is no one else.
40 You shall keep his statutes and his commandments which I command you today, that it may go well with you and with your children after you, and that you may prolong your days in the land which the LORD your God gives you for all time.

The biblical claim that there is one God is not an introductory idea later discarded by the New Testament. It remains in place. Christians do not have permission to solve difficult passages about the Father and Son by quietly adding more gods. Nor does the word person mean three separate human-style individuals who happen to cooperate. The language is meant to preserve what Scripture reveals, including the unity of God's being. If a proposed explanation requires three divine beings, it has explained a different doctrine.

Read John 1:1-18

1 In the beginning was the Word, and the Word was with God, and the Word was God.
2 The same was in the beginning with God.
3 All things were made through him. Without him, nothing was made that has been made.
4 In him was life, and the life was the light of men.
5 The light shines in the darkness, and the darkness hasn’t overcome it.
6 There came a man sent from God, whose name was John.
7 The same came as a witness, that he might testify about the light, that all might believe through him.
8 He was not the light, but was sent that he might testify about the light.
9 The true light that enlightens everyone was coming into the world.
10 He was in the world, and the world was made through him, and the world didn’t recognize him.
11 He came to his own, and those who were his own didn’t receive him.
12 But as many as received him, to them he gave the right to become God’s children, to those who believe in his name:
13 who were born, not of blood, nor of the will of the flesh, nor of the will of man, but of God.
14 The Word became flesh and lived among us. We saw his glory, such glory as of the only born Son of the Father, full of grace and truth.
15 John testified about him. He cried out, saying, “This was he of whom I said, ‘He who comes after me has surpassed me, for he was before me.’ ”
16 From his fullness we all received grace upon grace.
17 For the law was given through Moses. Grace and truth were realized through Jesus Christ.
18 No one has seen God at any time. The only born Son, who is in the bosom of the Father, has declared him.

John places two statements beside each other. The Word was with God, and the Word was God. The distinction is real, and the deity is real. Later, the Word becomes flesh. John has not described an ordinary man who gradually earns divine status. The One through whom creation came into existence enters the creation. That makes the incarnation astonishing, but it doesn't make the Son identical to the Father. The text supplies both truths, and an explanation needs to account for both.

A useful distinction is between a mystery and a contradiction. A contradiction asserts and denies the same thing in the same respect. A mystery may exceed complete understanding without making that error. Christians do not say God is one person and three persons in exactly the same sense. They say one divine being and three persons. That vocabulary does not explain everything about God. It identifies the boundaries of what is being confessed. The right question is whether those boundaries accurately preserve the biblical witness. Demanding that God fit every feature of created personality would assume at the beginning that He must be a creature.

Read John 14:15-26

15 If you love me, keep my commandments.
16 I will pray to the Father, and he will give you another Counselor, that he may be with you forever:
17 the Spirit of truth, whom the world can’t receive, for it doesn’t see him and doesn’t know him. You know him, for he lives with you and will be in you.
18 I will not leave you orphans. I will come to you.
19 Yet a little while, and the world will see me no more; but you will see me. Because I live, you will live also.
20 In that day you will know that I am in my Father, and you in me, and I in you.
21 One who has my commandments and keeps them, that person is one who loves me. One who loves me will be loved by my Father, and I will love him, and will reveal myself to him.”
22 Judas (not Iscariot) said to him, “Lord, what has happened that you are about to reveal yourself to us, and not to the world?”
23 Jesus answered him, “If a man loves me, he will keep my word. My Father will love him, and we will come to him and make our home with him.
24 He who doesn’t love me doesn’t keep my words. The word which you hear isn’t mine, but the Father’s who sent me.
25 “I have said these things to you while still living with you.
26 But the Counselor, the Holy Spirit, whom the Father will send in my name, will teach you all things, and will remind you of all that I said to you.

Jesus speaks of the Father sending another Helper. That doesn't fit the idea that one person simply changes names as the story progresses. The Son addresses the Father, and the Spirit is sent to dwell with believers. The Spirit teaches and bears witness; He is not spiritual electricity. At the same time, these actions are united in purpose. The Father isn't reluctant to save while the Son argues Him into it. Salvation expresses the will and love of the one triune God.

Read Ephesians 1:3-14

3 Blessed be the God and Father of our Lord Jesus Christ, who has blessed us with every spiritual blessing in the heavenly places in Christ,
4 even as he chose us in him before the foundation of the world, that we would be holy and without defect before him in love,
5 having predestined us for adoption as children through Jesus Christ to himself, according to the good pleasure of his desire,
6 to the praise of the glory of his grace, by which he freely gave us favor in the Beloved.
7 In him we have our redemption through his blood, the forgiveness of our trespasses, according to the riches of his grace
8 which he made to abound toward us in all wisdom and prudence,
9 making known to us the mystery of his will, according to his good pleasure which he purposed in him
10 to an administration of the fullness of the times, to sum up all things in Christ, the things in the heavens and the things on the earth, in him.
11 We were also assigned an inheritance in him, having been foreordained according to the purpose of him who does all things after the counsel of his will,
12 to the end that we should be to the praise of his glory, we who had before hoped in Christ.
13 In him you also, having heard the word of the truth, the Good News of your salvation—in whom, having also believed, you were sealed with the promised Holy Spirit,
14 who is a pledge of our inheritance, to the redemption of God’s own possession, to the praise of his glory.

This isn't merely a technical question for people who enjoy theological terminology. Paul describes Christian salvation in relation to the Father, Son, and Spirit. A believer's access to God, adoption, and hope are bound up with these truths. Water changing between ice, liquid, and vapor is a popular illustration, but it suggests one thing changing modes. That is precisely the misunderstanding to avoid. An analogy that is easy to remember can be especially troublesome when the part remembered is wrong.

Hold together what Scripture gives: one God, the Father truly God, the Son truly God, the Spirit truly God, and real personal distinctions. An illustration that loses one of those facts has stopped helping. Christian worship can be reverent without pretending the infinite God can be reduced to a household object.

Consider your perspective

The Trinity directs Christian worship toward the one God revealed as Father, Son, and Holy Spirit. The mystery invites reverent attention to Scripture rather than reducing God to an illustration that erases His personal distinctions.

Put it into practice

Read Ephesians 1 and notice the work attributed to the Father, Son, and Spirit. Let those observations guide your thanksgiving, without trying to make a household analogy explain everything.

Reflect and respond

  • Where does an analogy fail to preserve the biblical distinctions?
  • How does Ephesians 1 shape Christian praise?
  • Why is personal distinction different from division into three gods?
