THE TRINITY CLEARLY AFFIRMED
The clearest reference to Jesus’ deity in the New Testament comes at the opening of John’s gospel. It reads, “In the beginning was the Word [that is, the Logos], and the Word was with God, and the Word was God” (1:1). In that first sentence, we see the mystery of the Trinity, because the Logos is said to have been with God from the beginning. There are different terms in the Greek language that can be translated by the English word with, but the word that is used here suggests the closest possible relationship, virtually a face-to-face relationship. Nevertheless, John makes a distinction between the Logos and God. God and the Logos are together, but they are not the same.
Then John declares that the Logos not only was with God, He was God. So in one sense, the Word must be distinguished from God, and in another sense, the Word must be identified with God.
The apostle says more. He adds: “He was in the beginning with God. All things were made through him, and without him was not any thing made that was made. In him was life, and the life was the light of men” (vv. 2–4). Here we see eternality, creative power, and self-existence attributed to the Logos, who is Jesus.
The New Testament also states that the Holy Spirit is divine. We see this, for instance, in Jesus’ triune formula for baptism. By the command of Christ, people are to be baptized in the name of the Father, of the Son, and of the Holy Spirit (Matt. 28:19). Likewise, Paul’s closing benediction in his second letter to the Corinthians reads, “The grace of the Lord Jesus Christ and the love of God and the fellowship of the Holy Spirit be with you all” (13:13). The apostles also speak of the Father, Son, and Spirit cooperating to redeem a people for Themselves (2 Thess. 2:13–14; 1 Peter 1:2).
In these and many other passages in the New Testament, the deity of the Father, the Son, and the Holy Spirit is set forth explicitly or implicitly. When considered together with the Bible’s clear teaching as to the oneness of God, the only conclusion is that there is one God in three persons—the doctrine of the Trinity.
