Glen Butner concerning EFS

I am currently working on a book review of Glen Butner's book on the topic of ESS. In the meantime, here is an excerpt from the book which is well apprreciated by me:

Opponents of EFS have often accused those who support eternal submission of Arianism, and for this reason EFS theologians are accused of offering an inadequate theology. The accusation of Arianism is inaccurate. EFS theologians are quite clear that they are speaking of the divine persons when they speak of eternal submission, so it simply is not the case that they necessarily abandon the homoousios when speaking of the Son’s submission to the Father. This objection would only work if EFS advocates used categories like ousia, nature, person, and hypostatis with an identical meaning to pro-Nicene thought. They do not. Therefore, EFS should be seen as one of a number of modern efforts to explain the Trinity in a different manner than the pro-Nicene tradition. In this manner, EFS is more akin to social trinitarianism, for example, than Arianism. [D. Glenn Butner Jr., The Son who Learned Obedience: A Theological Case against the Eternal Submission of the Son (Eugene, OR: Pickwick Publishing, 2018), 194]
