At the center of Cusanus's thought, since its inception, is the exploration of human means and forms to obtain an adequate and precise concept of the Absolute or the Infinite. This study focuses on the analysis of the essential developments of the concept of God by Nicholas of Cusa from the years 1459 to 1464, which can be regarded as the culmination of his intellectual journey, as they achieve a speculative and argumentative level through conceptual innovations that enable a genuinely philosophical and thus Christian logic of infinity that transcends conventional parameters.
