My class on Christology is all but over for the semester, with only a quiz and a paper remaining. The class focused on the major Christological controversies of the 4th - 8th centuries, i.e. on the heresies of Arianism, Apollinarianism, Nestorianism, Monophysitism, Monothelitism, Monoenergism, and Iconoclasm.
In regards to the latter, I found this anecdote edifying:
"One day, a monk from Nicomedia was summoned before the emperor, who said to him contemptuously: 'Stupid monk, do you not see that anyone can walk on the image of Jesus Christ without being disrespectful to his person?' Quick to retort, the monk threw a coin stamped with the emperor's portrait onto the palace floor and responded: 'In that case, I am permitted to walk on your face without dishonoring you!' The emperor's assistants stopped him in the act, and the monk was put to death for having insulted the emperor's image."
