God, 3
Continuity with the Old Testament
The New Testament builds entirely on the foundation of Old Testament monotheism. Jesus and the apostles inherited and affirmed the God revealed through the Law and the Prophets: one, living, personal, holy, righteous, merciful, and sovereign over all creation. When asked about the greatest commandment, Jesus quoted the Shema: "Hear, O Israel: The Lord our God, the Lord is one" (Mark 12:29, citing Deuteronomy 6:4). Paul affirmed the same: "For us there is one God, the Father, from whom are all things and for whom we exist" (1 Corinthians 8:6).
Yet while building on the Old Testament, the New Testament transcends it. The last traces of particularism disappear. God can no longer be understood as the deity of one nation but is the God of all peoples, "who shows no partiality" (Acts 10:34). The worthy attributes of God articulated by the prophets and psalmists — his power, wisdom, love, faithfulness, and justice — are not replaced but are placed in a new relationship to humanity through Jesus Christ.
God as Father
The most transformative element in the New Testament understanding of God is Jesus' revelation of God as Father. While the Old Testament occasionally uses paternal imagery for God (Isaiah 63:16; Hosea 11:1), Jesus made fatherhood the dominant way of speaking about God. He addressed God as "Abba, Father" (Mark 14:36), a term of intimate trust, and taught his disciples to pray "Our Father in heaven" (Matthew 6:9).
Jesus' experience of divine fatherhood was unique: "No one knows the Son except the Father, and no one knows the Father except the Son and anyone to whom the Son chooses to reveal him" (Matthew 11:27). Yet through his work, this intimate relationship becomes accessible to believers. Paul writes that believers receive "the Spirit of adoption as sons, by whom we cry, 'Abba! Father!'" (Romans 8:15; Galatians 4:6). The fatherhood of God thus becomes the defining framework for understanding both God's character and the believer's identity.
The Deity of Christ and the Emerging Trinitarian Understanding
The most revolutionary development in the New Testament doctrine of God is the growing conviction that Jesus Christ is himself God. This conviction did not arise from Greek philosophical speculation but from the earliest Christian experience of the risen Christ. Within the New Testament itself, we find a trajectory from implicit claims to explicit affirmations.
Jesus exercised divine prerogatives: forgiving sins (Mark 2:5-7), accepting worship (Matthew 28:17), claiming existence before Abraham (John 8:58), and declaring, "I and the Father are one" (John 10:30). The Gospel of John opens with the direct statement: "In the beginning was the Word, and the Word was with God, and the Word was God" (John 1:1). Thomas confesses the risen Christ as "My Lord and my God!" (John 20:28).
Paul identifies Jesus with the divine identity by applying Old Testament passages about Yahweh to Christ (Philippians 2:9-11, echoing Isaiah 45:23). Colossians declares that "in him the whole fullness of deity dwells bodily" (Colossians 2:9). Hebrews opens by describing the Son as "the radiance of the glory of God and the exact imprint of his nature" (Hebrews 1:3).
The Holy Spirit as Divine Person
Alongside the revelation of the Son, the New Testament presents the Holy Spirit not as an impersonal force but as a divine person who acts, speaks, and can be grieved (Acts 13:2; Ephesians 4:30). Jesus promised to send "another Helper" (John 14:16), using language that implies the Spirit is a person like himself. The Spirit searches the depths of God (1 Corinthians 2:10-11), distributes gifts as he wills (1 Corinthians 12:11), and intercedes for believers (Romans 8:26-27).
The triadic pattern of Father, Son, and Spirit appears in several New Testament texts: the baptismal formula (Matthew 28:19), Paul's benediction (2 Corinthians 13:14), and the opening of 1 Peter (1 Peter 1:2). While the formal doctrine of the Trinity was articulated in later centuries, the raw materials are thoroughly embedded in the New Testament's witness to one God known in three persons.
God's Love as the Central Attribute
If any single attribute defines the New Testament's portrait of God, it is love. "God is love" (1 John 4:8, 16) is a statement unique to John and represents the New Testament's crowning insight into the divine nature. This love is not sentimental but costly: "God shows his love for us in that while we were still sinners, Christ died for us" (Romans 5:8). The cross becomes the definitive revelation of who God is — not distant power but self-giving love.
Jesus' parable of the Prodigal Son (Luke 15:11-32) portrays a father who runs to embrace a returning sinner, overturning conventional notions of divine dignity. Paul proclaims that nothing in all creation can separate believers from "the love of God in Christ Jesus our Lord" (Romans 8:39). The New Testament thus culminates in a vision of God who is sovereign yet intimate, holy yet gracious, just yet merciful — all held together in the person and work of Jesus Christ.
Biblical Context
The New Testament doctrine of God pervades every book. Key passages include the Synoptic Gospels' presentation of God as Father (Matthew 6:9; Luke 15), John's Prologue (John 1:1-18), Paul's theological expositions (Romans 1-11; 1 Corinthians 8:6; Colossians 1:15-20), Hebrews 1, and 1 John 4. The trinitarian pattern appears in Matthew 28:19, 2 Corinthians 13:14, and Ephesians 1:3-14.
Theological Significance
The New Testament transforms Israel's monotheism by revealing God as Trinity: Father, Son, and Holy Spirit. This is not the addition of new gods but the deepening of the understanding of the one God through his self-revelation in Christ and the Spirit. The centrality of love in the New Testament doctrine of God, demonstrated supremely in the cross, provides the foundation for all Christian ethics, soteriology, and eschatology.
Historical Background
The New Testament doctrine of God emerged in a context shaped by Second Temple Judaism's strict monotheism and by the broader Greco-Roman world's philosophical reflection on the divine. Greek philosophy, particularly Platonic and Stoic thought, influenced the conceptual vocabulary used by New Testament writers (especially the Logos concept in John). However, the content of the New Testament doctrine of God is rooted in the historical events of Jesus' life, death, and resurrection rather than in philosophical speculation. The formal trinitarian creeds of Nicaea (325 AD) and Constantinople (381 AD) later articulated what the New Testament texts presented narratively and doxologically.
