How do we know the doctrine of the Trinity is true?
Answered in 88 sources
The doctrine of the Trinity is affirmed through scriptural revelations of God as one essence in three distinct persons: God the Father, God the Son, and God the Holy Spirit.
The doctrine of the Trinity, which teaches that there is one God in three persons, is established through various biblical texts. The Gospel of John opens by declaring the Word was both with God and was God (John 1:1), affirming the co-existence and co-equality of Christ with the Father. Moreover, Jesus’ baptism illustrates the distinct persons of the Trinity when the Father speaks from heaven, the Son is baptized, and the Holy Spirit descends like a dove (Matthew 3:16-17). This mystery is foundational to understanding God's nature and acts in history.
