The theology of Karl Rahner is perhaps more than anything else a theology investigating the ground and modes of man's freedom in God. Here this primary concern of his provides the focus for a series of reflections on all aspects of the present situation Catholics find themselves in. The author well understands the dilemma of the Catholic who feels the Second Vatican Council and events subsequent to it have meant the end of enduring Christianity; he understands as well the feelings of the Catholic who believes the Church is not changing quickly enough into a truly Christian community. He addresses himself to both these extremes and then writes provocatively and concretely about how the two should cooperate in "the transition of an established Church to a Church of the community of faith".
