Today we recall the great truth about our God. Three persons. One God. Trinity. And there is no point trying to explain it. We only know this truth about God because God revealed it to us.
In the early Church, there was some confusion about why Jesus was baptized by John. We see even John the Baptist has a question about the appropriateness of his baptizing Jesus. The gospel of John mentions a few times that John the Baptist was not the light, not the one coming into the world. So why, then? As we have seen all throughout the Christmas season, the Baptism of Jesus is one more way we see the divinity of Jesus manifest.
