Cyril's Problem
...for Cyril, the Logos acts as the agent of all that is done in the human nature, a position that raises a host of problems, including how the integrity of the human nature could be preserved. In other words, how can we speak of truly human experiences? Moreover, ascribing suffering to the Logos while affirming divine impassibility proves to be, at best, incoherent.
