Born and raised right here in Baltimore to a prominent lawyer and a devoted and godly mother, Machen wrestled deeply with his own commitment to the orthodox faith in his schooling from Johns Hopkins to the prominent theological schools in Germany, served in World War I, and settled in as professor at the most prominent Presbyterian seminary in the United States – Princeton – before seeing his entire world come under attack.  But he answered with a cogent, clear, and powerful defense of Reformed orthodoxy that resulted in the formation of two new institutions: Westminster Seminary and the Orthodox Presbyterian Church.
