Page "Cyril of Alexandria" Paragraph 21

According to Cyril's theology, there were two states for the Son: the state that existed prior to the Son ( or Word / Logos ) becoming enfleshed in the person of Jesus and the state that actually became enfleshed.

Thus, only the Logos incarnate suffered and died on the Cross and therefore the Son was able to suffer without suffering.

Cyril's concern was that there needed to be continuity of the divine subject between the Logos and the incarnate Word — and so in Jesus Christ the divine Logos was really present in the flesh and in the world.
