"The Council of Nicaea in 325 AD marked the beginning of a new era in Christianity. For the first time, doctrines were organized into a single creed. The Nicene and Post-Nicene Fathers did most of their writing during and after this important event in Church history. Unlike the previous era of Christian writing, the Nicene and Post-Nicene era is dominated by a few very important and prolific writers. In Volume III of the 14-volume collected writings of the Nicenes and Post-Nicenes (first published between 1886 and 1889), readers will find a complete collection of Saint Augustines writings concerning Christian doctrine and ethics. On the Holy Trinity is one of his most important works, and Augustine spent a significant amount of time crafting it. Among the ethical considerations covered in the second half of the book readers will find essays on virginity, lying, patience, and proper care for the dead."Schaff, Philip is the author of 'Nicene and Post-Nicene Fathers: First Series, Volume III St. Augustine', published 2007 under ISBN 9781602065949 and ISBN 1602065942.
