The world around us often views firm convictions about truth and error as the height of arrogance—even dangerous. Yet many Christians persist in holding to the ecumenical creeds and confessions of faith such as the Westminster Confession of Faith. Are they foolish, misguided, and prideful? Or are they wise, Scriptural, and humble? Samuel Miller, one of the first professors at Princeton Theological Seminary in New Jersey, believed that creeds and confessions were vital for maintaining the unity and purity of the visible church, and in this brief work he sets forth arguments for this position and engages with objections to it. As Dr. Jonathan Master writes in his preface to this work, “[Miller’s] case is as compelling today as it was when it was initially written.”
