This is the first installment of a five-part series called, "5 Great Sermons from Church History." This is not meant to indicate that these are the greatest or the best sermons, or even the five most important in the history of the church. However, these sermons were selected based on historical significance, content, accessibility (both good translations and comprehensibility), and each as exemplary of the particular era in which it occurred. Given the scope, the five sermons stretch over the entirety of church history. Extreme redaction is unavoidable with such a project. Each of the entries will take a similar approach, namely: Brief background on speaker and sermon, redacted block quote to capture the heart of sermon, and brief commentary on the whole sermon.
