What is the Trinity?
Christians speak of God as Father, Son and Holy Spirit — one God, yet three Persons — and the word "Trinity" is the shorthand for that truth. It raises immediate questions: where does Scripture teach it, does it mean three Gods, and why does it matter to an ordinary believer?
One God, revealed in three
The starting point is not arithmetic but revelation. God has made Himself known in a way that holds both truths together at once.
A J PollockThere is abundance of teaching in the Holy Scriptures that God reveals Himself as Father, Son and Holy Spirit, not three Gods, but a Triune God. Scripture teaches that the Father is God, the Son is God, the Holy Spirit is God, yet one God indivisible.
A word not found in the Bible
Some object that "Trinity" never appears in Scripture. One writer answers that objection head on, pointing to the scene at the Jordan river where the Father spoke, the Son stood, and the Spirit descended.
William KellySuch is the early and immense fact recorded in the Gospels, a clear witness to "the Trinity." What sympathy can one have with those who overlook such a fact and stumble over the term? Why be so tied to the letter, and so anxious to get rid of a word because it is not in the Bible? The thing is distinctly there.
A mystery we cannot measure
No one claims to explain it. The limit is built into what we are.
A J PollockThe Holy Trinity — Three in One, and One in Three — is in its essence a mystery beyond human understanding, even the understanding of the renewed mind of the believer. In the very nature of things this must be so. How can the creature comprehend the Creator; the finite, the Infinite?
That is why the ordinary human meaning of "person" has to be handled with care when we use it of God.
A J PollockIn human language, when we speak of a person we think of a separate being, separate existence, separate will, different characteristics, thoughts and plans belonging to each one and not shared with others. Carry that human thought into the subject before us, and the truth of the Trinity is entirely twisted and lost. Instead of the Trinity — Father, Son and Spirit, ONE God — we would have three Gods, an absolute impossibility.
When it came into the light
Israel was taught that God is one. The fuller unveiling waited for Christ.
William KellyDuring the Jewish period God, though known to be one, was not known as He is. "He made known His ways to Moses, His acts to the people of Israel" (Ps. 103:7)... It was only Jesus who made Him truly known, as we see in that act of incomparable grace when He was fulfilling all righteousness by being baptised by John in the Jordan (Matt. 3:13-17). There, as the Holy Spirit descended on Him, the Father from heaven proclaimed Him to be His beloved Son. The Trinity stood revealed. It is in the persons of Father, Son, and Holy Spirit that God, the one God, is really known.
Three Persons, not three roles
A common misunderstanding treats Father, Son and Spirit as three costumes worn by one Person. Writers reject this sharply.
William J HockingNor is this truth to be weakened in the least degree. The one who allows no more in the Godhead than three aspects of one Person is not a Christian, but a deceiver and an antichrist... the Godhead not merely in three characters but in Three Persons; and so distinct that the Father could send the Son (1 John 4:14), and the Holy Spirit descend on that Son in the presence of the Father and in the awareness of the Son (Mark 1:10-11).
Distinct, yet never acting apart
The way the Spirit's coming is described shows how the three are bound together in one action.
A J PollockJohn 14:26 tells us that the Holy Spirit is sent by the Father in the Name of the Son; chapter 15:26 tells us the Lord Jesus sends the Holy Spirit from the Father; chapter 16:13 says, "When the Spirit is come," that is, the Spirit comes on His own initiative. So we have the Father sending the Spirit; the Son sending the Spirit; the Spirit coming. These statements could not be true unless the Father, Son and Holy Spirit are ONE God.
Why it touches your salvation
This is not a topic for specialists. Each Person has a part in a Christian ever becoming one.
J T MawsonThe Father would have sent the Son in vain, and the Son would have come and died and risen again for nothing as far as men are concerned, if the Holy Spirit had not come to give an answer in the hearts of men to the grace of the Father and the Son... There could have been no Christianity, not one of us would have been a Christian, apart from the Spirit. He convicted us of our sinful, lost condition; it was by Him through the Word that we were born again.
Some advise leaving such a high subject alone. That advice is answered plainly.
A J PollockIf God has revealed Himself, as we see in the Scriptures, surely He wants that revelation to be received and valued above everything else. Our highest blessing springs from the revelation God has been pleased to make of Himself. The more we understand of these things, the more the very foundation of Christianity is laid in our souls, and the shaping power of such truth leads to the true worship of God as nothing else can.
Summary
- Revealed, not reasoned. God is unknowable by searching; what we have of Him is what He has shown — Father, Son and Holy Spirit, one God.
- Revealed in Christ. Israel knew God is one; at the Jordan the Father spoke, the Son stood and the Spirit descended, and the Trinity stood revealed.
- Revealed as Persons. Not one Person in three costumes — the Father sends, the Son comes, the Spirit descends, and commentators treat any lesser view as a denial of God.
- Revealed as one. The Father sends the Spirit, the Son sends the Spirit, and the Spirit comes: distinct Persons, one undivided God.
- Revealed for you. The Father planned, the Son died and rose, the Spirit brought it home — and this revelation is the foundation of worship, not a puzzle to avoid.
