what does the bible say?
The Athanasian Creed was written sometime in the late fifth or early sixth century as a clear summary of biblical teaching about the Trinity and the person of Christ. Though not written by Athanasius, it reflects his commitment to defending the full deity of the Son and the Spirit. It remains one of the most detailed early statements of orthodox belief.
The creed affirms that Scripture teaches the oneness of God (Deuteronomy 6:4; Isaiah 44:6, 45:5) while also presenting the Father, Son, and Spirit as fully divine (Genesis 1:2; Exodus 3:2-6; Isaiah 63:10). It says that the Father is God (1 Peter 1:2), the Son is God (John 1:1 and Titus 2:13), and that the Spirit is God (Acts 5:3–4). All three were present at Jesus’ baptism (Matthew 3:16–17). The creed also reflects the biblical pattern of describing the Son as begotten (John 1:14) and the Spirit as proceeding (John 15:26), while maintaining that all three share the same eternal glory (John 17:5).
The creed also summarizes the incarnation, in which the eternal Son took on true humanity (Philippians 2:6–8; Hebrews 2:14–17) without ceasing to be God. It affirms Christ’s death, resurrection, ascension, and future return (1 Corinthians 15:3–4; Acts 1:9–11) and the final judgment of all people (John 5:28–29).
