Bible readings:

But who can endure the day of his coming? Who can stand when he appears? For he will be like a refiner’s fire or a launderer’s soap. He will sit as a refiner and purifier of silver; he will purify the Levites and refine them like gold and silver. Then the Lord will have men who will bring offerings in righteousness, and the offerings of Judah and Jerusalem will be acceptable to the Lord, as in days gone by, as in former years.

John the Baptist prepares the way

In the fifteenth year of the reign of Tiberius Caesar – when Pontius Pilate was governor of Judea, Herod tetrarch of Galilee, his brother Philip tetrarch of Iturea and Traconitis, and Lysanias tetrarch of Abilene – during the high-priesthood of Annas and Caiaphas, the word of God came to John son of Zechariah in the wilderness. He went into all the country around the Jordan, preaching a baptism of repentance for the forgiveness of sins. As it is written in the book of the words of Isaiah the prophet:

‘A voice of one calling in the wilderness,
“Prepare the way for the Lord,
    make straight paths for him.
Every valley shall be filled in,
    every mountain and hill made low.
The crooked roads shall become straight,
    the rough ways smooth.
And all people will see God’s salvation.”’
