Subordinationism is a Trinitarian doctrine wherein the Son (and sometimes also the Holy Spirit) is subordinate to the Father, not only in submission and role, but with actual ontological subordination to varying degrees.[1] It posits a hierarchical ranking of the persons of the Social Trinity, implying ontological subordination of the persons of the Son and the Holy Spirit.[2] It was condemned as heretical in the Second Council of Constantinople.[3][4]
It is not to be confused with Arianism, as Subordinationism has been generally viewed as closer to the Nicene-Constantinopolitan view. While Arianism was developed out of it, it did not confess the personality of the Holy Spirit and the eternity of the Son.[5][6]
