How were the three persons of the Godhead manifested at Jesus' baptism?

Les explains that at Christ's baptism the three persons of the Godhead were manifested together: God the Father spoke and identified Jesus as His beloved Son, and the Holy Spirit descended. This displays the co-equal Trinity, each person distinct yet present.

The baptism provides a clear picture of the Godhead in action.
