"The close relationship between Jesus and the Church is highlighted in the story of Paul’s conversion. … Note here Jesus’ exact words: “Why do you persecute me?” Saul could have easily answered, “I’m not persecuting you – I am going after your disciples.” However, it seems Jesus’ words illustrate precisely the critical point which is emphasized over and over again in the book of Acts: Jesus is to be identified with his Church. … Thus, as Christ lived in his earthly body, he now lives in the Church. What he did in his earthly body he now does in his Mystical Body."
