Catechism of the Catholic Church

"In the beginning was the Word... and the Word was God... all things were made through him, and without him was not anything made that was made." The New Testament reveals that God created everything by the eternal Word, his beloved Son. In him "all things were created, in heaven and on earth... all things were created through him and for him. He is before all things, and in him all things hold together." The Church's faith likewise confesses the creative action of the Holy Spirit, the "giver of life," "the Creator Spirit" ("Veni, Creator Spiritus"), the "source of every good." (241, 331, 703)
