Excellent read for Protestants and Roman Catholics alike. Patristic studies can easily degrade into "I have more church father quotes than you do" arguments. Fr. Ramsey has done a fine job of maintaining an irenic tone. The material is presented in a thematic style that gives a good overview of patristic thought on a given subject. For Protestant readers who are starting out in this subject I would recommend "Getting to Know the Church Fathers: An Evangelical Introduction" By: Bryan Litfin. That book will give a good introduction to the topic. The Ramsey book will then go beyond that a bit.
