This week, let’s read the first article of the Augsburg Confession. This one is short and sweet because it deals with controversies that were settled long before the reformation. Basically, this article says we agree with the council of Nicaea that God is Triune.
All Christian churches, whether they are Roman Catholic, Eastern Orthodox, or one of the many Protestant churches that later emerged, acknowledge that there is one God in three persons. Throughout history, heretical groups have tried to deny or subvert this doctrine. To our finite minds, it might not seem logical. However, this is how God has revealed himself. Non-Trinitarian churches are not Christian.
For a fuller, more in-depth explanation of the Trinity, the best place to start is the Nicene and Athanasian Creeds.
