The dignity of the human person is rooted in his creation in the image and likeness of God (Article 1); it is fulfilled in his vocation to divine beatitude (Article 2). It is essential to a human being freely to direct himself to this fulfillment (Article 3). By his deliberate actions (Article 4), the human person does, or does not, conform to the good promised by God and attested by moral conscience (Article 5). Human beings make their own contribution to their interior growth; they make their whole sentient and spiritual lives into means of this growth (Article 6). With the help of grace they grow in virtue (Article 7), avoid sin, and if they sin they entrust themselves as did the prodigal son1 to the mercy of our Father in heaven (Article 8). In this way they attain to the perfection of charity.
