First Reading: Genesis 1:1–5
In the beginning when God created the heavens and the earth, 2the earth was a formless void and darkness covered the face of the deep, while a wind from God swept over the face of the waters. 3Then God said, "Let there be light"; and there was light. 4And God saw that the light was good; and God separated the light from the darkness. 5God called the light Day, and the darkness he called Night. And there was evening and there was morning, the first day.
Second Reading: Acts 19:1–7
While Apollos was in Corinth, Paul passed through the interior regions and came to Ephesus, where he found some disciples. 2He said to them, "Did you receive the Holy Spirit when you became believers?" They replied, "No, we have not even heard that there is a Holy Spirit." 3Then he said, "Into what then were you baptized?" They answered, "Into John's baptism." 4Paul said, "John baptized with the baptism of repentance, telling the people to believe in the one who was to come after him, that is, in Jesus." 5On hearing this, they were baptized in the name of the Lord Jesus. 6When Paul had laid his hands on them, the Holy Spirit came upon them, and they spoke in tongues and prophesied — 7altogether there were about twelve of them.
Gospel: Mark 1:4–11
4John the baptizer appeared in the wilderness, proclaiming a baptism of repentance for the forgiveness of sins. 5And people from the whole Judean countryside and all the people of Jerusalem were going out to him, and were baptized by him in the river Jordan, confessing their sins. 6Now John was clothed with camel's hair, with a leather belt around his waist, and he ate locusts and wild honey. 7He proclaimed, "The one who is more powerful than I is coming after me; I am not worthy to stoop down and untie the thong of his sandals. 8I have baptized you with water; but he will baptize you with the Holy Spirit."
9In those days Jesus came from Nazareth of Galilee and was baptized by John in the Jordan. 10And just as he was coming up out of the water, he saw the heavens torn apart and the Spirit descending like a dove on him. 11And a voice came from heaven, "You are my Son, the Beloved; with you I am well pleased."
