Photinians imply mortality; Tertullian assigns body yet vindicates immortality

The Photinians of this age lay down those principles from which the mortality of the soul must necessarily be concluded, in the Racovian Catechism, in order to attack the union of the divine and human natures in Christ, in the chapter on the knowledge of Christ. So they say that two substances adverse in properties cannot come together into one person, as mortal and immortal are. Tertullian ascribes a corporeal nature, yet does not take away immortality, but rather vindicates it sharply. But he seems to call every created thing that truly subsists a body, as also Hilary in his Matthew canon 5; therefore he ought not to be numbered among those errors: yet what he ascribes in On the Soul chapter 9 — length, breadth, and height, by which philosophers measure bodies — cannot be excused or explained by any convenient reason. And chapter 36: The soul, he says, sown in the womb together with the flesh, together with it also obtains sex. These things are to be trembled at, not laughed at, as Augustine witnesses in On Genesis Literally book 20, the last chapters.
