Peter and the apostles have by now intrepidly responded to the inspirations of the Holy Spirit. They’re seeing how the Risen Lord has begun something beautiful which they know cannot be contained and is meant to spread throughout the world. The voice of Jesus, the Good Shepherd, risen from the dead, begins to get clearer and clearer: “Go therefore and make disciples of all the nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, teaching them to observe all things that I have commanded you; and lo, I am with you always, even to the end of the age” (Matthew 28:19).
