I am applying for the diaconate program in our diocese, and this fast-reading book was an excellent introduction to the role of the deacon in the Catholic Church. Despite the renewed emphasis on deacons since Vatican II, there is still a lot of ignorance about the deacons' responsibilities and the nature of their sacrament of ordination. This book explains how deacons are different from priests and bishops, and yet how they are similar, as well. I have found it invaluable in my discernment about being called to the diaconate.
