Every person brought into existence reflects the likeness of God. Our value is in being, not doing.
388. We proclaim that all human beings exist purely and simply by the love of God who created them, and by the love of God who preserves them at every moment. The creation of man and woman in his image and likeness is a divine event of life, and its source is the faithful love of the Lord. Hence, only the Lord is author and master of life, and human beings, his living image, are always sacred, from their conception, at all stages of existence, until their natural death, and after death. The Christian view of human beings makes apparent their value, which transcends the entire universe: “God has shown us unsurpassably how he loves all human beings, and thereby confers infinite dignity on them.”(John Paul II, Message to the handicapped, Angelus November 16, 1980.)
