The Trinity is truly a mystery. This doctrine teaches that the God of Christianity is one in His essence but three in His persons—the Father, the Son, and the Holy Spirit. Though the word Trinity is not found in the Bible, there is no doubt that the Scriptures teach this triune nature of God. Yet the concept still challenges our finite minds.

In this Crucial Questions booklet, Dr. R.C. Sproul carefully explains the doctrine of the Trinity, stressing that Christians worship one God who manifests Himself in three distinct persons. He shows what the Bible teaches and outlines the chief errors on this doctrine that have afflicted the church. Above all, he affirms that while this truth is difficult to understand, it is not contradictory. Rather, it is a beautiful expression of the biblical teaching on the nature of God.

As a gifted communicator, R.C. Sproul has helped many believers grow in their understanding of such matters as the nature of God, the history of redemption, and the manner in which we are saved. Now Dr. Sproul’s lucid teaching on these vital matters is available in a series of concise booklets that are perfect for personal learning and refreshing, as well as small-group study. For a quick introduction to matters at the very core of the Christian life, for yourself or a friend, consider the Crucial Questions booklets from Reformation Trust Publishing.
