Catholic social teaching is … 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.
As the Catechism of the Catholic Church explains, “To receive in truth the Body and Blood of Christ given up for us, we must recognize Christ in the poorest, his brethren” (no. 1397).
Every human being is created in the image of God and redeemed by Jesus Christ… Every person, from the moment of conception to natural death, has inherent dignity and a right to life consistent with that dignity.
