The philosopher and religious thinker Simone Weil is one of the most radical theological thinkers of the mid-twentieth century. Weil's thinking of God is radical at core because her conception of the act of creation dissents from every established Christian tradition: Weil posits that God must contract God's power for something to exist as other than God. God cannot therefore create out of infinite power, but only by electing powerlessness, relinquishing power, becoming Dieu impuissant (i.e., weak or powerless God). This chapter revises her legacy and places her thought within the radical theological tradition.
