The throne [θρόνος] of God and of the Lamb will be in the city, and His slaves [δοῦλοι] will serve Him. (John 22:3b; HCSB)
The Two Primary Complementarian Positions
The Eternal Relations of Authority Position
1. Their primary method is to construct an understanding of the Trinity from the biblical ground up.
2. The primary analogy they have chosen to organize the complex biblical witness about the immanent relations of the Father, the Son, and the Holy Spirit in the biblical text is a relational analogy, that of personal "relations of authority."
3. The ὁμοούσιος (homoousios) of the Nicene tradition is affirmed. God the Father and God the Son, along with the Holy Spirit, share the same nature.
4. Most ERA proponents seem to operate from a modern Calvinist perspective.
The Other Complementarian Position
1. These theologians seek to construct a biblical theology of the Trinity, but with an ear sensitive to the theological exegesis of the classical tradition.
2. The primary analogy they have chosen to organize the complex witness of the biblical text regarding the immanent Trinity is the Cappadocian and Augustinian language of "eternal generation" with regard to the Son and "eternal procession" with regard to the Holy Spirit. This theological analogy is relational, but differs from that of the ERA theologians. Where the ERA theologians stress relations of authority, the others use the ontological language of "relations of origin" and "modes of subsistence" or simply "ordered relations" (τάξις, taxis).
3. The ὁμοούσιος (homoousios) of the Nicene tradition is affirmed. God the Father and God the Son, along with God the Holy Spirit, share the same nature. Also receiving major emphasis is the divine attribute of simplicity.
4. Many of these proponents also operate from a modern Calvinist perspective. Some follow B.B. Warfield's disjunction between the immanent Trinity and economic Trinity, while others lean toward a modified version of Karl Rahner's identification between the immanent Trinity and the economic Trinity. Some appeal to the Augustinian presentation of the Trinity with its psychological analogy or love analogy. Some appeal to the Reformed covenant of redemption. Others appeal to Calvin's origination of the Son from himself as God (αὐτόθεοϛ, autotheos). In various ways, the traditional emphasis on the unity of the three persons is thus emphasized.
