In 2009-2010 I began to hear of a discussion about the eternal subordination of Jesus in the Trinitarian scheme. It’s main proponents are Wayne Grudem from Phoenix Seminary and Bruce Ware from Southern Seminary. The eternal subordination of Jesus basically proposes an eternal hierarchy of authority among the three persons of the Trinity. The Father is the supreme authority with the Son and Spirit eternally submitted to his authority. Millard Erickson provides insight in a recent book.
