1.1 La théorie du Big Bang n'exclut-elle pas la foi en Dieu ?

Création ou hasard?

Certaines personnes pensent que l’Église est contre la science et que les chrétiens doivent donc aussi réfuter le Big Bang. L'inverse est vrai

La théorie du Big Bang a même été initialement suggérée par un prêtre catholique, Georges Lemaître (†1966), pour laquelle il a reçu une reconnaissance officielle de l’Église. L’idée duBig Bang s'accorde très bienavec la croyance que Dieu créa le monde "ex nihilo" (à partir de rien).

La théorie du Big Bang n'exclut pas la foi en Dieu. Au contraire, on peut la comprendre comme la manière dont Dieu a commencé à créer l'univers.
The Wisdom of the Church

How did God create the universe?

God created the universe freely with wisdom and love. The world is not the result of any necessity, nor of blind fate, nor of chance. God created “out of nothing” (ex nihilo) (2 Maccabees 7:28) a world which is ordered and good and which he infinitely transcends. God preserves his creation in being and sustains it, giving it the capacity to act and leading it toward its fulfillment through his Son and the Holy Spirit. [CCCC 54]

Is the world a product of chance?

No. God, not chance, is the cause of the world. Neither in its origin nor with respect to its intrinsic order and purposefulness is it the product of factors working “aimlessly”.   

Christians believe that they can read God’s handwriting in his creation. To scientists who talk about the whole world as a random, meaningless, and aimless process, Pope John Paul II pointed out in reply in 1985, “Given a universe in which there is such a complex organization of its elements and such a wonderful purposefulness in its life, talking about chance would be equivalent to giving up the search for an explanation of the world as it appears to us. In fact it would be tantamount to accepting effects without cause. It would be an abdication of human reason, which in this way would be refusing to think and to search for a solution to problems". [Youcat 43]

This is what the Church Fathers say

It is the nature of things which come into being to derive their origin from what is already existing. And it seemed to me that it might be said with equal truth, that nothing is eternally co-existent with God distinct from himself, but that whatever exists has its origin from him. [St. Methodius, On Free Will, Chap. 2 (ML 18, 244)]
