The onto-theological constitution of metaphysics has assigned God to being. Aristotle's Metaphysics prepared this path by linking the first philosophy, the science of being qua being, and theology. Even the biblical God did not escape being since Gilson established a "Metaphysics of Exodus." Thanks to Marion's phenomenology of givenness, and by making Love the first of God's names, we can think its indifference to being so. By analyzing the speech of praise and the declaration of love, we show that in order to wrest God from his ontological site, it is necessary to go through the perlocutionary function of language, the only one able to say God without being (it). It is then the real foundation of Marion's phenomenology.
