Continuous change would now appear to be a permanent feature of Roman Catholicism. It was not always so, and as a result there is confusion for some. By skilfully selecting central themes, the author gives a comprehensive yet succinct account of the main theological advances as well as the most significant writers of the past three decades. She interprets clearly what is happening in the church today, yet she is not confrontational. Monika Hellwig's book should be helpful to all who have reflective interest in their religious faith and a desire to understand broader patterns within the church. It should give assurance to those who have endeavoured to put into practice the spirit of Vatican II and may also interest conservatives who have reacted negatively to modern theology.
