3.2 God–Father, Son, and Holy Spirit

God has revealed Himself as Father, Son, and Holy Spirit. Thus God can be recognised as the triune God. This self-revelation of God constitutes the basis for the doctrine of the Trinity. God's actions in history and creation are executed as the respective works of the Father, the Son, and the Holy Spirit. God reveals Himself as Creator, Redeemer, Reconciler, and Maker of the new creation. God reveals His triune nature in Jesus' life–at His baptism, transfiguration, crucifixion, resurrection, and ascension into heaven–as well as at the outpouring of the Holy Spirit on Pentecost: He is Father, Son, and Holy Spirit.


The mystery of the divine Trinity comes to expression in various ways in the Old and New Testaments. However, Holy Scripture does not mention the term or provide any doctrine on the Trinity. This doctrine was recognised and formulated in the early church on the basis of biblical evidence.
