Zephaniah 3:14-20
Isaiah 12:2-6
Philippians 4:4-7
Luke 3:7-18

By tradition, the Third Sunday in Advent has been called Gaudete Sunday, a day to “rejoice” as we turn in hope and expectation toward the celebration of Christmas, the twelve-day Feast of the Incarnation. While the designation Gaudete stems from this week’s Second Lesson, Philippians 4:4-7, Gaudete in Domino semper, “rejoice in the Lord always,” the remaining readings hardly neglect joyful hope.

Despite the people of Judah concluding that “The LORD will not do good, nor will he do harm” (Zephaniah 1:12b), the prophet envisions a new day where a remnant “shall do no wrong and utter no lies” (Zephaniah 3:13). Then the carnival of celebration envisioned in our reading will erupt, a celebration of singing based on the unshakeable faith that “the LORD, your God, is in your midst” (3:17) and, in fact, is joining the party. It is a time when even the lame and outcast will lose their shame and be at home (3:19-20).

Much the same can be said of the “songs of Isaiah” (Isaiah 12:1-6). No matter how uncertain the international political system might be, God is trustworthy. When the community takes that to heart, it is always appropriate to sing these two short verses reminiscent of the songs of Moses and Miriam (Exodus 15:1-21). These songs are so powerful that they continue to be used as worship acclamations. There are few more powerful texts than: “Surely God is my salvation; I will trust and not be afraid, for the LORD God is my strength and my might; he has become my salvation” (Isaiah 12:2).

As good as it is to “rejoice,” we know that the new day has not arrived as we wonder how to respond to the worldwide refugee crisis, cholera in Yemen, mass shootings in the U.S., and the Fourth National Climate Assessment. It is no surprise that with high confidence this assessment predicts more floods, higher temperatures, more wildfires, reduced crop yields, transportation difficulties, and the appearance of previously rare diseases ( Because the current administration released this report on so-called “Black Friday” (better celebrated as “Buy Nothing Day”), the hope was that it would be buried in this frenzy of consumption. Certainly it is not the kind of news that should spark community celebration.

But then neither should being in prison. Yet that is precisely the venue from which Paul urges the Philippian community to “rejoice.” He is not alone in projecting hope in the midst of a situation which could only be called desperate. As Walter Brueggemann suggests, the prophetic imagination bearing hope often emerges from the unlikeliest places: from a birth to an elderly couple and a young, unmarried woman, from a wilderness retreat enjoyed by thousands with seemingly no food, from capital punishment using brutal crucifixion, or from a Roman prison (Walter Bureggemann, The Prophetic Imagination, Minneapolis: Fortress, 2001, p. 102).

Perhaps this is because in all of these cases that which is seen as “ordinary and proper” (especially when backed up by imperial coercive power) is not ultimate. Paul makes this clear in Philippians when he urges hearers to be “minded,“ not by an Ayn Rand’s “virtue of selfishness,” but as Christ Jesus, “who, though he was in the form of God, did not regard equality with God as something to be exploited, but emptied himself, taking the form of a slave…” (Philippians 2:6-7a). He continues this line of thought by providing assurance that it is the peace of God beyond understanding which will “stand guard” (froreo) over the hearts and minds of the faithful. No longer is it a centurion, as Paul saw daily in prison, who provides for the security of the community; now the Pax Romana is replaced by the Pax Christi, a peace extended to the whole creation.

This search for peace and safety is at the center as Luke’s narrative of the ministry of John the Baptist continues. “You brood of vipers! Who warned you to flee from the wrath to come?” (Luke 3:7). Security can never be found by leaving one’s city or village for a mere splash in the Jordan River. John’s baptism entails repentance and bearing fruits worthy of a new outlook on life. This is especially true in the face of the temptation to join Lot’s wife in looking back to embrace what seems like a safe past.

John sees through this tactic. “Do not begin to say to yourselves, ‘We have Abraham as our ancestor…’”(Luke 3:8). As the Baptist uncovers this dodge, we see the sharp contrast between what John prepares the people to look ahead for and relying solely on pedigree—even from Abraham. An important clue is the word “begin” (archomai). Luke’s entire narrative moves God’s story forward, beginning with the communities of Abraham-Sarah and Moses-Miriam, but extending to all people and living creatures (Luke 2:32). No wonder John’s mission of preparation and baptism for repentance takes for granted congruence between cleansing water and bearing good fruit. Anything less neglects the coming future and needs to feel the axe; it is good only for burning (Luke 3:9).

Much the same is true of current so-called “populist” movements that hearken back to a non-existent past when everyone had a good job, there was little crime, no environmental challenge, all went to church, and the dizzying assortment of “others” had not demanded a place at the table. Because this “past” can never be re-created, it is used primarily as a vague source of values aimed at choking off immigration, eliminating equal rights, and elevating an “ancestral group” on behalf of which authoritarians seek to rule. This backward looking ideology never bears good fruit as it spreads racism, sexism, homophobia, and neglects eco-justice. It makes nothing “great again,” but powerfully draws attention and energy away from responding to real needs.

What then is this “good fruit” that meets Luke’s intention in creating his “orderly account?” (Luke 1:1). Which is exactly what the crowds asked John the Baptist: “What then shall we do?” (Luke 3:10, 12, 14). Whether it is a matter of sharing clothing and food or exercising the power to collect taxes or serve in the military, the answer is the same: live out an “ethics of the Magnificat.” As Mary sings, “He has brought down the powerful from their thrones, and lifted up the lowly; he has filled the hungry with good things, and sent the rich away empty” (Luke 1:52-53). Like the provision of daily bread, all is gift—whether the harvest of wheat or the call to service. These gifts of creation become fruitful when they are shared as freely as they are received.

It is no surprise that John’s presence and teaching led people to “rejoice” that they had found the Messiah. John will have none of this. While he provides a water bath, the more powerful coming one will baptize with “the Holy Spirit and fire” (Luke 3:16), a clear reference to the Day of Pentecost (Acts 2). Once again we are reminded of the Exodus, where the spirit-wind parted the seas, while the people were led by a pillar of fire. This new exodus will go through the very gates of death to open not only the scriptures (Luke 24:27, 32, 45) and the eyes of the disappointed couple (Luke 24:31), but also open the whole creation to reconciliation-shalom (Luke 24:47). Baptism into the death and resurrection of this coming one (Romans 6:1-11) means a life of fruitful working toward ecojustice in opposition to the forces of greed that continue to destroy creation, described as “chaff” slated for a good burning (Luke 3:17b).

This powerful and gracious opening of the Earth to reconciliation (Luke 24:47) is echoed in baptismal liturgies. Candidates for baptism, parents, and sponsors are empowered to fulfill these central responsibilities: to “proclaim Christ through word and deed, care for others and the world God has made, and work for justice and peace” (Evangelical Lutheran Worship, Minneapolis: Augsburg-Fortress, 2006, p. 228). As we engage in pre-baptismal education and proclaim reconciliation, we are called to remember that our lives are formed to care for the whole creation.

Advent provides a fruitful time of opportunity for this message. While there is pressure to engage in endless shopping to find the most pleasing gifts, to load the calendar with a round of parties, card writing, and all the rest, the community of faith offers counter-cultural freedom to carve out time and space to focus on what is most important. While Christmas is hardly “Jesus’ birthday,” the phrase “Whose Birthday Is It?” had some real usefulness. Now broaden that to learn how to prepare for celebrating the Trinity dwelling with us—and we have something worth “rejoicing” in.
