This book is a wonderfully precise and concise summary of the Church's dogmatic theology, and with due respect to a previous reviewer, it is not a bit out-of-date. It is not intended to be an expanded or detailed discussion of theological problems, so of course it is recommended that people also read the works of orthodox theologians such as Hans Urs von Balthazaar, Henri de Lubac, and (especially) John Paul II; and they should also examine the beautiful teachings of Vatican II. Nevertheless, the dogmas summarized in the _Fundamentals_ are timeless.
What makes this volume so valuable is its precision and clarity: one can easily look up a particular doctrine of the Church and see what status it has---that is, how formally it has been defined by the Church. Moreover, for every point of doctrine it states with exact precision which opinions are consonant with Church teaching, which are tolerated, and which are contrary. These are things that are beyond the scope of, say, the new Universal Catechism. However, all well-informed Catholics ought to know them.
The _Fundamentals_ is highly recommended, and I urge all Catholics who want to know their faith well to get the book along with the new Universal Catechism.
