We, the Church militant, must proclaim the love of Christ to the world. While on earth Jesus prepared His Church by giving authority to His disciples and by setting Saint Peter as the Church's head. Most importantly, He gave The Church "The Great Commission": to baptize all nations in the name of the Father and of the Son and of the Holy Ghost.
