"Get up, be baptised and wash your sins away, calling on his name." (Acts 22:16)
Standing on the steps of the barracks with the commander's permission, Paul signals to the crowd and speaks to them in Aramaic. He establishes his credentials as a fellow Jew: born in Tarsus of Cilicia, brought up in Jerusalem, educated under Gamaliel according to the strict interpretation of the Law, zealous for God as all of them are today. He persecuted this Way to the death, binding and putting both men and women in prison, as the high priest and the whole council can testify. Then he tells the story of the Damascus road. The crowd listens quietly until he mentions that the Lord told him to go to the Gentiles. Then they raise their voices and shout: rid the earth of him, he's not fit to live.
The recount of Paul's conversion includes a detail not found in Acts 9: the words of Ananias when he came to restore Paul's sight. Ananias says: the God of our ancestors has chosen you to know his will and to see the Righteous One and to hear words from his mouth. You will be his witness to all people of what you have seen and heard. Get up, be baptised and wash your sins away, calling on his name. The imperative form of the command is striking: Baptism is not merely a rite of initiation. It is a washing, an effective action that accomplishes what it signifies. The Catechism calls Baptism the sacrament of regeneration through water and the word, by which sins are forgiven and new life is given (CCC 1213).
As the soldiers are about to flog Paul to extract information, he asks: is it legal to flog a Roman citizen who hasn't even been found guilty? The centurion reports to the commander, who is alarmed that he has had Paul bound. Paul's Roman citizenship, which will eventually take him to Rome and to the seat of the Empire, is a providential instrument in the hands of the God who is directing the entire narrative toward the ends of the earth.
Brothers and sisters, Paul told the same story of his conversion to a hostile crowd in the Temple precincts that had just been trying to kill him. The story of what God has done in your life is the most powerful apologetic you have. It cannot be argued with. Share it. Even to people who do not want to hear it. The telling is itself an act of witness.
Lord Jesus, you appeared to Paul on the Damascus road and washed his sins away in the waters of Baptism. Renew in us the grace of our own Baptism. Make us bold to tell our story to every crowd, hostile or welcoming. Through Christ our Lord. Amen.
