142. But if the Holy Spirit is of one will
and operation with God the Father, He is also of one substance, since
the Creator is known by His works. So, then, it is the same
Spirit, he says, the same Lord, the same God. 1 Cor. xii. 5. And if you say Spirit, He is the
same; and if you say Lord, He is the same; and if you say God, He is
the same. Not the same, so that Himself is Father, Himself Son,
Himself Spirit [one and the selfsame Person]; but because both the
Father and the Son are the same Power. He is, then, the same in
substance and in power, for there is not in the Godhead either the
confusion of Sabellius nor the division of Arius, nor any earthly and
bodily change.
