Some of my earliest childhood memories center on being with my family in worship on the Lord’s Day. In the Reformed and Presbyterian churches that we attended, expository preaching, hymn-singing, and prayer were fixed elements of worship, as were the historic creeds and confessions of the Christian church. We regularly confessed the Apostles’ Creed and the Nicene Creed—or some particular doctrinal statement out of the Westminster Confession of Faith, Westminster Shorter Catechism, or Heidelberg Catechism. Our pastors cited doctrinal statements from the Westminster Shorter Catechism in their sermons. Though I was unaware of it at the time, these historic doctrinal formulations were shaping my young mind in regard to biblical doctrine, worship, and the Christian life. Over a decade ago, I had the privilege of planting a Reformed and Presbyterian church. I enthusiastically incorporated many of the historic creeds and confessions into our worship service for the express purpose of instruction—as well as for the preservation of the core truths of the Christian faith and the worship of God.
