While they understand the past Catholic declarations and doctrines on justification and salvation, they seem to miss point of Catholic theology. The Catholic Church never recounts what has been previously said but slowly and methodically reform, while still affirming past councils and statements.[v] That is to say they don’t seem to affirm that the Joint Declaration on the Doctrine of Justification has much weight as it really does, nor do they think the anathemas thrown have been rescinded.[vi] In truth, they have not ‘been rescinded’ but that they do not apply to the Common Understanding set out in the Joint Declaration which can be seen as a win for Christian unity on salvation, a deeply central issue. But I ultimately cannot recommend this book based on their synthesis of Catholic Theology. While almost exclusively using the Roman Catholic Catechism as a source of theology they miss the last 50 years or so of Catholic and Protestant dialogue and the resulting declarations and upholding them in the same light. In all I do think it is worth the read but it seems to fall short of gracefully comparing the Catholic teaching to Protestant teaching.
