These three volumes are not for people who have read no theology. But they are certainly not for the specialist alone. Although there are some difficult passages, much of it is rewarding and easily grasped. Father Fransen's belief in theology as something intelligent and intelligible is shown forth. In presenting them in the form of three moderately priced paperbacks we hope that students of theology, at whatever level, may be able to obtain the books for them selves rather than have to borrow them. If the demand is sufficient an edition of the three volumes in a single library edition will be made available later.
