A selected quote from the Catechism of the Catholic Church in honor of the Year of Faith (October 11, 2012 - November 24, 2013)
355 "God created man in his own image, in the image of God he created him, male and female he created them." Man occupies a unique place in creation: (I) he is "in the image of God"; (II) in his own nature he unites the spiritual and material worlds; (III) he is created "male and female"; (IV) God established him in his friendship.
356 Of all visible creatures only man is "able to know and love his creator". He is "the only creature on earth that God has willed for its own sake", and he alone is called to share, by knowledge and love, in God's own life. It was for this end that he was created, and this is the fundamental reason for his dignity:
What made you establish man in so great a dignity? Certainly the incalculable love by which you have looked on your creature in yourself! You are taken with love for her; for by love indeed you created her, by love you have given her a being capable of tasting your eternal Good.357 Being in the image of God the human individual possesses the dignity of a person, who is not just something, but someone. He is capable of self-knowledge, of self-possession and of freely giving himself and entering into communion with other persons. And he is called by grace to a covenant with his Creator, to offer him a response of faith and love that no other creature can give in his stead.
362 The human person, created in the image of God, is a being at once corporeal and spiritual. The biblical account expresses this reality in symbolic language when it affirms that "then the LORD God formed man of dust from the ground, and breathed into his nostrils the breath of life; and man became a living being." Man, whole and entire, is therefore willed by God.
363 In Sacred Scripture the term "soul" often refers to human life or the entire human person. But "soul" also refers to the innermost aspect of man, that which is of greatest value in him, that by which he is most especially in God's image: "soul" signifies the spiritual principle in man.
364 The human body shares in the dignity of "the image of God": it is a human body precisely because it is animated by a spiritual soul, and it is the whole human person that is intended to become, in the body of Christ, a temple of the Spirit:
Man, though made of body and soul, is a unity. Through his very bodily condition he sums up in himself the elements of the material world. Through him they are thus brought to their highest perfection and can raise their voice in praise freely given to the Creator. For this reason man may not despise his bodily life. Rather he is obliged to regard his body as good and to hold it in honor since God has created it and will raise it up on the last day.369 Man and woman have been created, which is to say, willed by God: on the one hand, in perfect equality as human persons; on the other, in their respective beings as man and woman. "Being man" or "being woman" is a reality which is good and willed by God: man and woman possess an inalienable dignity which comes to them immediately from God their Creator. Man and woman are both with one and the same dignity "in the image of God". In their "being-man" and "being-woman", they reflect the Creator's wisdom and goodness.
372 Man and woman were made "for each other" - not that God left them half-made and incomplete: he created them to be a communion of persons, in which each can be "helpmate" to the other, for they are equal as persons ("bone of my bones. . .") and complementary as masculine and feminine. In marriage God unites them in such a way that, by forming "one flesh", they can transmit human life: "Be fruitful and multiply, and fill the earth." By transmitting human life to their descendants, man and woman as spouses and parents cooperate in a unique way in the Creator's work.
374 The first man was not only created good, but was also established in friendship with his Creator and in harmony with himself and with the creation around him, in a state that would be surpassed only by the glory of the new creation in Christ.
