The idea for this text stems from the question of what are the cultural origins of relativism-ateism present in Western society in relation to bioethics. These principles are found in the philosophical interpretation of the figure of Jesus Christ. The hermeneutical criteria for deciphering the bioethical question today can be found mainly - not only - in the Christological philosophies of Kant, Hegel, Nietzsche, which have their origin in the Lutheran vision of Christ and which have led to the development of a vision of life as if God did not exist. Why, then, do not propose as an alternative, the idea of living life in the perspective of the existence of God, revealed by Christ because a world without the God of Christ is a world against Christ, that is, a world against man, against the life of man. The God revealed by Christ, therefore, has something to do with my bioethical choices: he is the reference for my bioethical discernment because Christ is the truth about the life of God and man, which consists in love for life, any kind of life, at any moment of its human development. 3
