"Salvation is found in no one else, for there is no other name under heaven given to mankind by which we must be saved." (Acts 4:12)
While Peter and John are speaking to the crowd, the priests, the captain of the Temple guard, and the Sadducees arrive and seize them. They are put in jail overnight because it is already evening. But many who heard the message believe, and the number of men grows to about five thousand. The next day the rulers, elders, teachers of the law, the high priest, and his family assemble in Jerusalem and bring Peter and John before them. They ask: by what power or what name did you do this?
Peter, filled with the Holy Spirit, answers. He identifies the lame man's healing as a good deed done in the name of Jesus Christ of Nazareth, whom they crucified and whom God raised from the dead. He quotes Psalm 118:22: the stone rejected by the builders has become the cornerstone. And then comes the most theologically precise statement in the book of Acts: Salvation is found in no one else, for there is no other name under heaven given to mankind by which we must be saved. The Catechism calls this the unique mediation of Christ: not because God's mercy is narrow, but because the Incarnation, Death, and Resurrection of the eternal Son is the one act by which the Father accomplished the salvation of the whole world (CCC 432).
The council sees the courage of Peter and John and are astonished because they are unschooled, ordinary men, and they take note that these men had been with Jesus. They cannot deny the healing; the man is standing right there. They command them to speak no more in the name of Jesus. Peter and John answer: judge for yourselves whether it is right in God's sight to obey you rather than God. For we cannot help speaking about what we have seen and heard. The council threatens them further and lets them go.
The community prays together when Peter and John return, asking for boldness to speak God's word and for the Lord to stretch out his hand to heal. The place where they are meeting is shaken and they are all filled with the Holy Spirit and speak the word of God boldly. They hold everything in common; there is no needy person among them. Great grace is on them all.
Brothers and sisters, Peter and John were unschooled and ordinary. Their authority before the council came not from credentials but from having been with Jesus. The question the council asked of them is the question the world asks of every Christian: by what power and in what name do you do what you do? The answer that changes everything is still the same answer.
Lord Jesus, there is no other name under heaven by which we must be saved. Give us the boldness of Peter and John: to speak that name without apology before councils and crowds, among friends and strangers, in every circumstance where the name needs to be spoken. Through Christ our Lord. Amen.
