The author praises Gratian’s zeal for instruction in the Faith, and speaks lowly of his own merits. Taught of God Himself, the Emperor stands in no need of human instruction; yet this his devoutness prepares the way to victory. The task appointed to the author is difficult: in the accomplishment whereof he will be guided not so much by reason and argument as by authority, especially that of the Nicene Council.

This discussion of the doctrinal positions of the evangelical Lutheran church addresses all the articles of faith.

"In the opinion of competent thinkers the Christian Faith of Schleiermacher is, with the exception of Calvin's Institutes, the most important work covering the whole field of doctrine to which Protestant theology can point. To say this is not necessarily to adopt either his fundamental principles or the detailed conclusions to which these principles have guided him. On all such matters a nearly unbroken controversy has long prevailed. Indeed, at the moment a formidable attack is being delivered upon his main positions by a new and active school of thought in Germany. But, whether for acceptance or rejection, it is necessary for serious students to know what Schleiermacher has to say."--Editors' preface, page [v]

Aurelius Ambrosius, better known in English as Saint Ambrose (c. between 337 and 340 - 4 April 397), was a bishop of Milan who became one of the most influential ecclesiastical figures of the 4th century. He was one of the four original doctors of the Church. There is a legend that as an infant, a swarm of bees settled on his face while he lay in his cradle, leaving behind a drop of honey. His father considered this a sign of his future eloquence and honeyed tongue. For this reason, bees and beehives often appear in the saint's symbology. After the early death of his father, Ambrose followed his father's career. He was educated in Rome, studying literature, law, and rhetoric. As bishop of Milan, he immediately adopted an ascetic lifestyle, apportioned his money to the poor, donating all of his land, making only provision for his sister Marcellina (who later became a nun),[2] and committed the care of his family to his brother. Ambrose also wrote a treatise by the name of "The Goodness Of Death". On the eve of setting out for the East, to aid his uncle Valens in repelling a Gothic invasion, Gratian, the Emperor of the West, requested St. Ambrose to write him a treatise in proof of the Divinity of Jesus Christ. Gratian's object in making this request was to secure some sort of preservative against the corrupting influence of Arianism, which at that time (a.d. 378) had gained the upper hand of Orthodoxy in the Eastern provinces of the Empire, owing to its establishment at the Imperial Court. In compliance with Gratian's wish, the Bishop of Milan composed a treatise, which now forms the first two Books of the De Fide. With this work the Emperor was so much pleased that on his return from the East, after the death of Valens at Hadrianople, he wrote to St. Ambrose, begging for a fresh copy of the treatise, and further, for its enlargement by the addition of a discourse on the Divinity of the Holy Spirit. The original treatise was, indeed, enlarged by St. Ambrose in 379, but the additional Books dealt, not with the Divinity of the Holy Spirit, but rather with new objections raised by the Arian teachers, and points which had either been passed over or not fully discussed already. In this way St. Ambrose's Exposition was brought into its present form.

Written by an L. A. County homicide detective and former atheist, Cold-Case Christianity examines the claims of the New Testament using the skills and strategies of a hard-to-convince criminal investigator. Christianity could be defined as a “cold case”: it makes a claim about an event from the distant past for which there is little forensic evidence. In Cold-Case Christianity, J. Warner Wallace uses his nationally recognized skills as a homicide detective to look at the evidence and eyewitnesses behind Christian beliefs. Including gripping stories from his career and the visual techniques he developed in the courtroom, Wallace uses illustration to examine the powerful evidence that validates the claims of Christianity. A unique apologetic that speaks to readers’ intense interest in detective stories, Cold-Case Christianity inspires readers to have confidence in Christ as it prepares them to articulate the case for Christianity.
