When the word church is mentioned, many people tend to think of a formal building with a steeple and stained-glass windows. For others, the word brings to mind the idea of a denomination. But the church is much more. In this booklet, R. C. Sproul carefully and clearly explains that the church is a body of people saved by Jesus Christ and regenerated by the Holy Spirit who live to glorify and enjoy God. Beginning with the ancient Nicene Creed, which affirms that the church is “one, holy, catholic, and apostolic,” Sproul provides accessible teaching on one of the most misunderstood of all Christian doctrines.
