Communion originates from the Trinity, where God exists as eternal love between the Father, Son, and Holy Spirit. God created humanity with the vocation and capacity for love and communion. Our highest calling is to enter into communion with God and one another. From the beginning, humanity was created for communion as seen in the union of man and woman. The Christian family, Church, and sacraments all serve to foster communion between people in line with our divine calling. Living in communion and unity as the Body of Christ is essential for our spiritual life and missionary work.
