CATECHISM OF THE CATHOLIC CHURCH
SECOND EDITION

Paragraphs 314–317

314 We firmly believe that God is master of the world and of its history. But the ways of his providence are often unknown to us. Only at the end, when our partial knowledge ceases, when we see God "face to face", will we fully know the ways by which - even through the dramas of evil and sin - God has guided his creation to that definitive sabbath rest for which he created heaven and earth.
315 In the creation of the world and of man, God gave the first and universal witness to his almighty love and his wisdom, the first proclamation of the "plan of his loving goodness", which finds its goal in the new creation in Christ.
316 Though the work of creation is attributed to the Father in particular, it is equally a truth of faith that the Father, Son and Holy Spirit together are the one, indivisible principle of creation.
317 God alone created the universe, freely, directly and without any help.
