Darren Summer has written a blog article which does in some sense bring more clarity to the trinitarian issue. I think it is a good question to ask of ERAS/ EFS proponents, as it helps in clarification.
Just to be clear, Nicene orthodoxy teaches that there is absolutely ZERO subordination or submission in the immanent Trinity. To say that Jesus is lesser in "being" or status or anything compared to the Father is heresy. But just as clearly, there IS "a structure of authority and submission" in the economic Trinity, which I take as the correct interpretation of ERAS/ EFS, although I don't like to use those terms ("structure of authority and submission") as the focus in the economic Trinity should not be about authority and submission, but about condescension and obedience.
For clarity's sake, I hope Drs. Grudem, Ware and CBMW can answer this most basic question. Then we can know definitively whether they are in error, or whether their critics are being uncharitable and making false accusations, as they currently seem to be doing.
