Understanding the Trinity—one God in three persons (Father, Son, and Spirit)—takes us into deep theological waters, where the simplest math fails us: 1 + 1 + 1 = 1.
Even though the word “Trinity” never appears in any Bible verses, God reveals himself throughout Scripture as one being. While we can’t find answers to every question about the Trinity, we can grow in our love for God by searching Scripture to discover how he reveals himself to us.

Quotes on the Trinity
Our view on this doctrine affects our views of other doctrines. If the Godhead does not consist of three persons equally divine and yet inseparably one, we must redefine one or more of those persons. Jesus may not be fully God, or if he is, he is a lesser deity than is the Father. The Holy Spirit is in some sense inferior to both the Father and the Son. The doctrine of the atonement is modified as well. Instead of a voluntary self-sacrifice by a member of the Godhead, it is something imposed on a human by God, and thus contains an element of injustice.
—Millard J. Erickson, Making Sense of the Trinity1
There was never a God who was not Father and Son together in the unity of the Spirit, coequal, coeternal in the essence of the divine being.
—Fred Sanders, Perspectives on the Trinity (course)2
The Trinity is the most important doctrine of the Christian faith. It’s our Christian understanding of God. We alone believe in a tripersonal God—that the one God is the Father, the Son, and the Holy Spirit.
—Kevin Giles, Perspectives on the Trinity (course)2
To speak of the one God of the Bible is to speak of the Father, Son, and Spirit—they are each God, but they are not each other.
—Brandon D. Smith, The Biblical Trinity3
The core of Christian thought is that God the Father has saved us by sending the Son and the Holy Spirit, and in doing that He has made known to us that God eternally is Father, Son, and Holy Spirit. So this is a judgment about the entire meaning of everything in the Bible, the entire plan of salvation as it bears on the question “Who is God?”
—Fred Sanders, Perspectives on the Trinity (course)2
Love is the quality of God’s Trinitarian nature. Trinitarian persons relate to each other in a loving second-person perspective: in a “you” sense, rather than in the “he, she, or it” senses. This intimate sharing is demonstrated in Jesus’ prayer to his Father in John 17. In this prayer Jesus speaks to the Father about a prior and preexistent relationship of shared knowledge and recognition (glory) before the creation of the world (John 17:5). He prays: “Now, Father, glorify me in your presence with the glory I shared with you before the world was created” (John 17:5 ceb). Jesus recalled the Father and Son’s shared memory of a common experience in which the divine persons acknowledged each other’s personhood and significance, which is what glorification is.
—Scott Harrower, God of All Comfort4
As we read the Scriptures, our default setting should be christological; we should constantly be asking, how does it speak about him? We read trinitarianly when we read christologically because that same God is the God who put on flesh and dwelt among us. The key to the unity of Scripture is the mystery of the Trinity in the incarnation of the Son.
—Brandon D. Smith, The Biblical Trinity5
Christians praise one God in three persons, the blessed Trinity. We do so by proclaiming God’s triune name in baptism (Matt. 28:19), by invoking his name in benedictions (2 Cor. 13:14), by binding ourselves to his name when confessing our faith (1 Cor. 8:6; 12:3), and by hymning his name in our songs, joining the chorus of heavenly beings with all the saints in heaven and earth (Rev. 4–5). Christians praise God the Trinity because he is supremely worthy of our praise. The blessed Trinity is supreme in being, beauty, and beatitude.
