Father Barron calls Peter and Paul “two indispensable men, the ones without whom the church never would have emerged and survived.” In telling each man’s story, Father Barron shows how the Holy Spirit worked through all the apostles and disciples to build the Church. Following the trail of these apostles as they took the Gospel to the ends of the earth, Father Barron presents the foundations of the apostolic faith, particularly the revelation of Christ’s resurrection from the dead.
