Eternal functional subordination

Eternal functional subordination or Eternal subordination of the Son is a Trinitarian doctrine which proposes a hierarchy within the trinity, where though the Son is ontologically equal to the Father, he is subordinate in role, obeying the Father in eternity. Advocates of eternal subordination generally see this as a model for human relationships. Eternal Subordination is contrasted with the view held by Augustine, where the obedience of the Son to the Father is only by virtue of His human nature. Two prominent modern advocates of the doctrine are Wayne Grudem and Bruce Ware, though they often use the monicker "eternal relations of authority and submission" to further nuance their view.

Although the doctrine of eternal functional subordination has been used to justify complementarian views, it has gained criticism from both complementarian and egalitarian theologians.
