The modernity advance is a mark in the history of Theology. And because of this progress, the anthropocentric character of modernity is also accentuated. The human being, with his creations and discoveries, walks to take the place of God and the classical Christian worldview, which characterizes a modern anthropological twist. Naturally, this situation of modern dualism involving human being and God asks for some reaction of the Christian theologies. Some of them find the solution for this problem at the human figure itself, making of it a new way through what is possible to talk about god. Such attitude characterizes an anthropological twist in the theology. This dissertation will show the basic attitudes of a theology that propose itself on realizing such anthropological twist, whose the main theorist is the Jesuit theologian Karl Rahner, emphasizing some of its developments about the question of God. This way will be done in order to make the exposition of Paul Tillich s theological construction about the question of God on his Systematic Theology possible, raising the hypothesis that he realizes the anthropological twist in his work, which is necessary to any theology that aims to react to the modern anthropocentrism. Thus, it shows that the possibility of God does not necessarily end in contempt for human being and his advances.
