From The Teachings of Catholic Church
Life and Dignity of the Human Person .
The Catholic Church proclaims that human life is sacred and that the dignity of the human person is the foundation of a moral vision for society. This belief is the foundation of all the principles of our social teaching. Human persons are willed by God; they are imprinted with God’s image. Their dignity does not come from the work they do, but from the persons they are. (Centesimus annus #11, St. John Paul II)
The world exists for everyone, because all of us were born with the same dignity. Differences of color, religion, talent, place of birth or residence, and so many others, cannot be used to justify the privileges of some over the rights of all. As a community, we have an obligation to ensure that every person lives with dignity and has sufficient opportunities for his or her integral development. (Fratelli Tutti #118, Pope Francis)
God created man and woman in his image.
The good Samaritan recognized the dignity in the other and cared for his life.
