{God is} incorporeal, immaterial, impalpable, beyond quantity and circumscription, beyond form and figure.
(The Image of God in Man according to Cyril of Alexandria, p. 22, quoting "Responsiones ad Teberium" 14)
Men of good sense who focus their minds' eyes sharply on the attributes of the ineffable Godhead, see it as existing beyond every created thing, transcending all acuity of intellect, being wholly outside bodily appearance and, as all-wise Paul says, "dwelling in light unapproachable" (1 Tim 6:16). But if the light surrounding it is unapproachable, how can one gaze on it? We see "in a glass darkly and know in part" (1 Cor 13:12). Deity, then, is wholly incorporeal, without dimensions or size and not bounded by shape.
(Cyril of Alexandria: Select Letters, p. 185, quoting "Doctrinal Questions and Answers" 1)
The Only Begotten did not become man only to remain in the limits of the emptying. The point was that he who was God by nature should, in the act of self-emptying, assume everything that went along with it. This was how he would be revealed as ennobling the nature of man in himself by making {human nature} participate in his own sacred and divine honors.
(On the Unity of Christ, p. 101)
{Christ was wearied (Jn 4:6), hungry (Mt 4:2) and required sleep (Mt 8:24).} Just as we say that the flesh {assumed in the incarnation} became his very own, in the same way the weakness of the flesh became his very own in an economic appropriation to the terms of the unification. So he is "made like his brethren in all things except sin alone" (Heb. 2:17).
(On the Unity of Christ, p. 107)
{For the salvation of the whole world Christ} wished to suffer, even though he was beyond the power of suffering in his nature as God, then he wrapped himself in flesh that was capable of suffering, and revealed it as his very own, so that even the suffering might be said to be his because it was his own body which suffered... Since the manner of the economy allows him blamelessly to choose both to suffer in the flesh, and not to suffer in the Godhead (for the selfsame was at once God and man)...(cf. 1 Pet. 4:1).
(On the Unity of Christ, p. 118)
We must not think that he who descended into the limitation of manhood for our sake lost his inherent radiance and that transcendence that comes from his nature. No, he had this divine fullness even in the emptiness of our condition, and he enjoyed the highest eminence in humility, and held what belongs to him by nature (that is, to be worshipped by all) as a gift because of his humanity.
(On the Unity of Christ, p. 123)
The Word was alive even when his holy flesh was tasting death... The body which lay under corruption became a body of life so as to become beyond death and corruption.
(On the Unity of Christ, p. 115)
