The challenging nature of the Trinity often puzzles us—especially since no one passage in the Bible explains it on its own. Early creeds were written to unite the church's beliefs about the doctrine, yet people still struggle to understand it even in our own time.This booklet explores the teaching on the Trinity all throughout the Bible and through history. It addresses how God is both one and tripersonal and goes on to define the Trinity and its implications for our Christian practice.Basics of the Faith booklets introduce readers to basic Reformed doctrine and practice. On issues of church government and practice they reflect that framework—otherwise they are suitable for all church situations.
