When you, O Lord, were baptized in the Jordan,
the worship of the Trinity was made manifest.
For the voice of the Father bore witness unto you,
calling you the beloved Son.
And the Spirit in the form of a dove
confirmed his word as sure and steadfast.
O Christ, our God who has appeared and enlightened the world,
glory be to you.
In this song there are references to the actions of each member of the Holy Trinity in the event of Jesus’ baptism. The authenticity of this event is verified by its inclusion in Belgic Confession, Article 9, in which all three persons are included—the voice of the Father, the Son in the water, and the Holy Spirit in the form of a dove: “So, in the baptism of all believers this form was prescribed by Christ: Baptize all people ‘in the name of the Father and of the Son, and of the Holy Spirit.’”
