Theoretical-Practical Theology Vol. II 17th-century Reformed theologian Petrus Van Mastricht wrote a comprehensive treatment of theoretical-practical theology. This extensive collection is gradually being made available in English by Todd Rester, lead translator of this massive work. The second volume, Faith in the Triune God, was released this year. Todd is an associate professor of church history at Westminster Theological Seminary in Philadelphia. Listen as Jonathan, James, and Todd discuss the priority and value Mastricht gave to the practical and pastoral aspect of theology in training church members—especially, new ones.
