The way the Father, Son and Spirit related at Jesus’s baptism was not a one time only event; the whole scene is full of echoes of Genesis 1. There at the creation, the Spirit also hovers, dove-like, over waters. And just as a Spirit, after Jesus’ baptism, would send him out into the lifeless wilderness, so in Genesis 1 the Spirit appears as a power by which God’s word goes out into the lifeless void. In the beginning, God creates by His Word (the Word that would later become flash), and He does so by sending out His Word in the power of the Spirit or Breath.
