Our Lord took great care to select those who would spread word of Him and His newly-found Church when He was no longer walking the earth. Given insight from the Holy Spirit, Saint Peter knew Our Lord was the Messiah and Jesus identified Peter as the head of His flock. Saint Paul was selected and called in a miraculous way to serve Our Lord. His ardent and unwaivering love of Our Lord drove his writing and his missionary work. Sweet and loving Saint John not only spread Our Lord’s Word via his written version of the Gospels, but he also cared for Our Blessed Mother for over 20 years after Our Lord died on the Cross. This booklet provides more details to help us better understand these three Apostles, to enlighten us regarding their Apostleship, and, in emulating them, to strengthen our love of God and our neighbors.
