About the Conference

“The grace of the Lord Jesus Christ and the love of God and the fellowship of the Holy Spirit be with you all.” - 2 Corinthians 13:14

The Trinity is the quintessential Christian doctrine, celebrating the biblical truth of one God in three Persons: Father, Son, and Holy Spirit.  The first council of the ancient church at Nicaea in 325 A.D. defended the Trinity along with the deity of Jesus Christ. Ever since the church has realized that to think in a Christian way is to think in terms of the Trinity. B. B. Warfield wrote that the Trinity brings us “the solution of the deepest and most persistent difficulties in our conception of God as infinite moral Being, and illuminates, enriches, and elevates all our thoughts of God.”

Vital as the Trinity is to Christian faith and doctrine, we live in a time when increasingly few believers are well informed about it. Without the Trinity to structure our thoughts of God, we easily become imbalanced and impoverished, some believers thinking only in terms of the Father, others of the Son, and still others of the Holy Spirit. But the Reformed faith has placed the Trinity at the center of its doctrine, especially when it comes to God’s saving work. As the famous acrostic TULIP works out, the heart of the Bible’s solution to the problem of sin is the Father ordaining, the Son accomplishing, and the Spirit applying our salvation. Our goal in this year’s conference is to elevate the doctrine of God as Three-in-One, displaying some of His glory, and working through the vast implications of the biblical teaching of the Trinity.

We are thrilled to be joined by an outstanding group of scholar-preachers for this much anticipated conference. Geoffrey Thomas has been pastor of Alfred Place Baptist Church in Aberystwyth, Wales for over forty years and is hailed as one of the great British preachers of our time. Robert Letham has written a standard text on the Trinity. Born and raised in London, he lives at present in Wales, serving as professor of Systematic and Historical Theology at the Union School of Theology. David Garner is Professor of Systematic Theology and dean of faculty at Westminster Theological Seminary. In addition, Jonathan Landry Cruse, author and pastor of Community Presbyterian Church in Kalamazoo, MI, and Jeffrey Stivason, pastor at Grace Reformed Presbyterian Church in Gibsonia, PA and seminary professor will be leading workshops. This is an exciting opportunity to learn from these highly qualified theologians and gifted preachers!

Whether you are a long-time supporter of the PCRT or if this will be your first time to join us, we look forward to meeting you and worshiping together as we delight in our Triune God.
