I recently heard an anti-Protestant pundit claim that Protestantism commits the error of Nestorianism in Christology. I thought of this as I happened to be reading a few sections of Calvin’s Institutes yesterday and ran across these statements:
“Away with the error of Nestorius, who in wanting to pull apart rather than distinguish the nature of Christ devised a double Christ…. Let us beware also, of Eutyches’ madness; lest, while meaning to show the unity of the person, we destroy either nature” (Institutes, 2.14.4).
“I have testified that we do not agree at all with Nestorius, who imagined a double Christ” (Institutes, 2.14.7).
