God, who is love, created all people in his image—male and female he created them—to share His love and therefore to reflect His love in the world and in their lives. Jesus Christ fully reveals who God is as a Triune communion of love—Father, Son, and Holy Spirit. He shows us the face of God, and shows us who we are, and who we are called to be.
“Our profession of faith begins with God, for God is the First and the Last, the beginning and the end of everything. The Credo begins with God the Father, for the Father is the first divine person of the Most Holy Trinity; our Creed begins with the creation of heaven and earth, for creation is the beginning and the foundation of all God’s works.” – Catechism of the Catholic Church, no. 198
The teaching authority of the Catholic Church, called the Magisterium, lies with all of the bishops who are led by the pope and guided by the Holy Spirit. The pope and bishops are the authoritative teachers in the Church.
The most basic principle of the Christian moral life is the awareness that every person bears the dignity of being made in the image of God. He has given us an immortal soul and through the gifts of intelligence and reason enables us to understand the order of things established in his creation. God has also given us a free will to seek and love what is true, good, and beautiful. Sadly, because of the Fall, we also suffer the impact of Original Sin, which darkens our minds, weakens our wills, and inclines us to sin. Baptism delivers us from Original Sin but not from its effects—especially the inclination to sin, concupiscence. Within us, then, is both the powerful surge toward the good because we are made in the image of God, and the darker impulses toward evil because of the effects of Original Sin.
But we should always remember that Christ’s dying and rising offers us new life in the Spirit, whose saving grace delivers us from sin and heals sin’s damage within us. Thus we speak of the value, dignity, and goal of human life, even with its imperfections and struggles. Human life, as a profound unity of physical and spiritual dimensions, is sacred. It is distinct from all other forms of life, since it alone is imprinted with the very image of its Creator.
Catholic social teaching is a central and essential element of our faith. Its roots are in the Hebrew prophets who announced God’s special love for the poor and called God’s people to a covenant of love and justice. It is a teaching founded on the life and words of Jesus Christ, who came “to bring glad tidings to the poor . . . liberty to captives . . . recovery of sight to the blind”(Lk 4:18-19), and who identified himself with “the least of these,” the hungry and the stranger (cf. Mt 25:45). Catholic social teaching is built on a commitment to the poor. This commitment arises from our experiences of Christ in the Eucharist.
“The whole liturgical life of the Church revolves around the Eucharistic sacrifice and the sacraments. There are seven sacraments in the Church: Baptism, Confirmation, Eucharist, Penance, Anointing of the Sick, Holy Orders, and Matrimony.” “Sacraments are “powers that comes forth” from the Body of Christ, which is ever-living and life-giving. They are actions of the Holy Spirit at work in his Body, the Church. They are “the masterworks of God” in the new and everlasting covenant.” – Catechism of the Catholic Church, no. 1113 & 1116
