Compendium of the Catechism of the Catholic Church

59. What did God create?
Sacred Scripture says, “In the beginning, God created the heavens and the earth” (Genesis 1:1). The Church in her profession of faith proclaims that God is the Creator of everything, visible and invisible, of all spiritual and corporeal beings, that is, of angels and of the visible world and, in a special way, of man.

60. Who are the angels?
The angels are purely spiritual creatures, incorporeal, invisible, immortal, and personal beings endowed with intelligence and will. They ceaselessly contemplate God face-to-face and they glorify him. They serve him and are his messengers in the accomplishment of his saving mission to all.

61. In what way are angels present in the life of the Church?
The Church joins with the angels in adoring God, invokes their assistance and commemorates some in her liturgy.

“Beside each believer stands an angel as a protector and shepherd leading him to life.” (Saint Basil the Great)

62. What does Sacred Scripture teach about the creation of the visible world?
Through the account of the “six days” of creation Sacred Scripture teaches us the value of the created world and its purpose, namely, to praise God and to serve humanity. Every single thing owes its very existence to God from whom it receives its goodness and perfection, its proper laws and its proper place in the universe.

63. What is the place of the human person in creation?
The human person is the summit of visible creation in as much as he or she is created in the image and likeness of God.

64. What kind of bond exists between created things?
There exist an interdependence and a hierarchy among creatures as willed by God. At the same time, there is also a unity and solidarity among creatures since all have the same Creator, are loved by him and are ordered to his glory. Respecting the laws inscribed in creation and the relations which derive from the nature of things is, therefore, a principle of wisdom and a foundation for morality.

74. What was the fall of the angels?
This expression indicates that Satan and the other demons, about which Sacred Scripture and the Tradition of the Church speak, were angels, created good by God. They were, however, transformed into evil because with a free and irrevocable choice they rejected God and his Kingdom, thus giving rise to the existence of hell. They try to associate human beings with their revolt against God. However, God has wrought in Christ a sure victory over the Evil One.
