Christmastime: what baptism reveals about Jesus and us

On this last Sunday of the Christmas season, the Lectionary presents themes that celebrate the Baptism of the Lord. The readings ask us to think about baptism and what it tells us about Jesus and us.

The first reading can be either Isaiah 42 or Isaiah 55:

• Isaiah 42 is by Second Isaiah, who spoke to the Jewish people in exile in Babylon in the sixth century BC. Today’s pericope includes the first servant song (Is 42:1-2), which focuses on the servant’s mission: to establish peace on earth, to be a covenant to Israel and a revelation to the nations, to open the eyes of the blind, and to proclaim liberation of captives. The Lectionary editors chose this reading because it describes a servant selected by God who will heal and free the people.
• Isaiah 55 is also by Second Isaiah. Today’s pericope focuses on the mystery of God’s thoughts to humans. God’s mercy (“turn to the Lord for mercy”) and generosity (“generous in forgiving”) motivate all to seek the Lord, but “God’s ways” remain a mystery to humans (“my thoughts are not your thoughts, nor are your ways my ways”). The Lectionary editors chose this reading because it emphasizes the mystery of God’s mercy and generosity, especially as revealed in God’s saving plan.

The second reading can be either Luke’s Acts of the Apostles or John the Elder’s first letter:

• Acts, written during the 80s, is by the same author as Luke’s gospel. Today’s pericope is from one of Acts’ kerygmatic speeches. This passage tells Jesus’ history as a series of God’s acts: God preaches the good news of peace in Jesus; God anoints Jesus; God is with Jesus when Jesus performs miracles. The Lectionary editors chose this reading because it contains the only reference to Jesus’ baptism outside the gospels.
• 1 John, written by a member of the Johannine community around 100 AD, continues many of John the Evangelist’s themes: believing, born-of-God, love, God’s commands, the world, water, blood, witness/testimony, and truth. Today’s pericope explains how Jesus’ baptism (“through water”) reveals Jesus (in his humanity) Christ (in his divinity) as “the coming one” foretold by the Baptizer. The Lectionary editors chose this reading because it highlights Jesus Christ as God’s Son and revelation of God’s saving love.

Mark’s gospel is the story of Jesus’ baptism, in which Mark again reveals who Jesus really is. Modern readers may miss cultural clues and context that were obvious to his first-century hearers.

• Leaving home and family. In the ancient Mediterranean world, family is the central social institution. Apart from family, an individual has no identity. Mark says that Jesus leaves his family and village (“came from Nazareth”) to be baptized “in the Jordan by John.” Mark’s hearers would be surprised that Jesus breaks his family ties. How could Jesus survive without a family?
• Jesus’ true paternity. The ancient world had only a primitive understanding of reproduction and had no tools to prove a child’s paternity. A baby became a son or daughter only when a father publicly acknowledged the child as his. Jesus became Joseph’s son when Joseph agreed to marry Mary who was not pregnant by him. Joseph’s acceptance of Jesus as his son gave Jesus honor and a family. When Jesus left Joseph’s family and village, God personally acknowledged him and revealed Jesus as God’s own son (“You are my beloved Son”). Mark’s hearers would recognize that God’s acceptance gives Jesus greater honor and a divine family.

This week’s readings, as all Christmas season readings, ask us to consider the meaning of Jesus’ self-revelation. The Isaiah readings reveal God’s servant and God’s saving plan. Acts reveals God working through Jesus. John’s letter identifies Jesus as the promised messiah and savior who is revealed through his baptism and his death. Mark reveals that Jesus is truly the Son of God. Baptism foretells and tells us who Jesus is. As disciples, our own baptisms are full of expectations and promises. Are we faithful to our baptismal promises? Do our words and actions reveal us every day as God’s adopted children? Do our baptismal lives reveal us as sisters and brothers of one divine family?
