“Without these five confessional statements – Scripture alone, Christ alone, grace alone, faith alone, and glory to God alone – we do not have a true church, and certainly not one that will survive for very long. For how can any church be a true and faithful church if it does not stand for Scripture alone, is not committed to a biblical gospel, and does not exist for God’s glory? A church without these convictions has ceased to be a true church, whatever else it may be.”
