The readings for the third Sunday of Advent put me in mind of one of the most significant themes in Catholic theology, namely, the play between nature and grace. St. Luke tells us that people came to John the Baptist, asking what they should do to reform their lives. John responds with good and very pointed moral advice. To the tax collectors he says, "Don't take more money than you ought" and to the soldiers he urges, "Do not practice extortion, do not falsely accuse anyone; be content with your pay." In so saying, he was addressing very common practices of that time and place. Tax collectors regularly demanded more money than was just and skimmed the surplus for themselves-which helps to explain why they were so unpopular. And soldiers-young men with weapons and too much time on their hands-predictably acted as bully-boys, extorting money through threats of violence.
John the Baptist is, quite sensibly, calling such people to decency and justice. As such, he stands with great philosophers, poets, social reformers, and religious figures. Plato, Aristotle, Cicero, Thomas Jefferson, and Martin Luther King, Jr. all summoned people to be just, "to render to each his due," in Plato's pithy formula. In point of fact, John, often called the last of the prophets, echoes his prophetic forebears-Isaiah, Jeremiah, Ezekiel, Amos, Hosea, etc.-all of whom urged Israel to walk the path of justice and care for the marginalized and poor.
So far, so natural. But then John adds something, which should take our breath away: "One mightier than I is coming. I am not worthy to loosen the thongs of his sandals," that is to say, perform a task that was considered too demeaning even for a slave. We just couldn't imagine Isaiah saying such a thing about Jeremiah, or Amos about Hosea, or Plato about Aristotle. What John the Baptist is signaling is the qualitative difference between himself (and the entire prophetic tradition that he represents) and the coming Christ Jesus. John was baptizing with water, but the one he announces will baptize with fire and the Holy Spirit.
Notice how the emphasis has shifted from the active to the passive. John told his audience that there were certain very definite things that they could do. But the one who is coming will not so much call for action on our part; rather, he will accomplish something that we, even in principle, could never accomplish for ourselves. He will dip us (baptizein) in the Holy Spirit, which is precisely the love that obtains between the Father and the Son, the love that God is. It is with this very love that he will set us on fire.
