In this issue of Credo Magazine, several pastors and theologians help us understand just how much doctrine matters for the Christian life and for the church. We will discover that doctrine infiltrates the songs we sing, the sermons we preach, and the way we counsel each other as disciples of Christ. We will learn that nothing could be more critical to a right relationship with God and others than sound doctrine. Whether we realize it or not, doctrine is a way of life. The Christian life depends entirely upon sound doctrine. In short, doctrine matters.
