On the night before He died, at the Last Supper, Jesus prayed with His Apostles. The heart of His prayer was simple; He asked the Father to give His followers the grace of unity: “that they may be one” (John 17:11), so that “the world may know that you sent me, and that you loved them even as you loved me” (John 17:23). The Father answered Jesus’ prayer. He sent the Holy Spirit to build up the Church that Jesus established on earth. He gave us the Sacrament of Baptism to make us members of His Church and unite us to Christ and one another. The other Sacraments He gave us to strengthen the bond created by our Baptism and heal that bond when it is broken by sin. God did not, however, take away our free will or force unity on us. He left us a choice. And that means the same fallen human nature that led men to crucify Jesus has also splintered the Father’s family, the Church.
