For almost two thousand years the Church has consistently professed and proclaimed the truth that the creation of the visible and invisible world is the work of God.
It has done this in continuity with the faith professed and proclaimed by Israel, the People of God of the old covenant.
Biblical scholars judge that the second account is more ancient.
It has a more figurative and concrete character; it addresses God by the name of "Yahweh," and for this reason it is known as the "Yahwistic source." The first account, later in time of composition, is more systematic and theological. It distributes the work of creation over a series of six days.
3) It is contrary to faith to assert that God is essentially identified with the world (pantheism) (DS 3023).
4) It is contrary to faith to maintain that creatures, even spiritual ones, are an emanation of the divine substance, or to affirm that the divine Being by its manifestation or evolution becomes everything (DS 3024).The author of the first chapter of Genesis wished to confirm the teaching contained in the Decalogue by inculcating the obligation to keep holy the seventh day.The account of the work of creation deserves to be read and meditated upon frequently in the liturgy and outside of it.Those same tendencies are present also in our century in certain developments of the exact sciences and of the atheistic ideologies.In the Constitution Dei Filius of the First Vatican Council we read: "This one true God, in his goodness and 'omnipotent power,' not to increase his own happiness, nor to acquire, but to manifest his perfection through the gifts he distributes to creatures, by a supremely free decision, 'simultaneously from the beginning of time drew forth from nothingness both the one creature and the other, the spiritual and the corporeal, that is, the angelic and the material, and then the human creature, who as it were shares in both orders, being composed of spirit and body'  " (DS 3002).Scholars have concluded that this text had its origin in the priestly and cultic circles, since the seventh day is presented as the day on which God rests.It proposes to man the worker the example of God the Creator.The creative power is not transmissible-incommunicabilis. 2) God freely created the world, without any exterior compulsion or interior obligation.He could create or not create; he could create this world or another one.Research on the origin and development of the individual species in nature does not find in this description any definitive norm or positive contributions of substantial interest.Indeed, the theory of natural evolution, understood in a sense that does not exclude divine causality, is not in principle opposed to the truth about the creation of the visible world, as presented in the Book of Genesis.
