The baptism of Jesus in the Jordan reveals two central truths of Christianity, one we think about a lot, and the other not so much. The one we think a lot about is the fact that Jesus is the promised Savior, the Messiah. He is the one described by Isaiah, the one God sent to take away the sins of the world and inaugurate a new, everlasting kingdom of justice and love. His baptism makes this evident by the descent of the Holy Spirit and God's voice ringing out from heaven. The truth of Christianity we think about less often is that of the Blessed Trinity. We always pray in the name of the Father, and of the Son, and of the Holy Spirit. We profess our belief every Sunday, when we pray the Creed, in the true God who is one and three: one in divine nature, and three in persons. The Father is fully God, the Son is fully God (he existed before his incarnation), and the Holy Spirit is fully God. All three are eternal, uncreated, and divine - separate persons, but one God. We don't believe in three Gods, but only one. And yet, this one God is three divine Persons. All three show up at the baptism of Jesus. The Son is Jesus. The Holy Spirit is the Spirit of God descending upon Jesus like a dove, from heaven and the Father is the voice from heaven saying, "This is my beloved Son." The reason we don't think too much about the Trinity is because it's often hard for us to understand. But now and then we should think about it - after all, God revealed it for a reason. In truth, our trying to understand God fully is like an infant trying to understand nuclear physics completely, or a monkey trying to play a Mozart violin concerto. In fact, the very existence of the concept indicates its truth. No human mind could have invented such a concept; only God could have revealed it. If our idea of God did fit into our small human minds, then God wouldn’t really be very much, would He? This is why God gives each of us the gift of Faith!
